Hello,
Looking for a bit of assistance regarding GT350 Power Steering.
If you look at the picture attached of the lower crank pulley (which is a C7 number) there is a "gap" between the alternator and P/S grooves.
With that in mind, to align the belt from the P/S pulley to the crank pulley there is a secondary 1/4" spacer on the long bolt holding the top of the P/S pump.
I tried a C6 pulley where there was no "gap", but that pulley would not even fit down in the hi-po balancer.
The only thing that is missing from my setup is the small bracket on the back of the pump to that same long bolt, but that is very thin and wouldn't make up the difference.
I'm stumped as to why my setup needs this additional 1/4" spacer added for alignment.
I would also appreciate any pictures that others might have so that I could compare. I searched through the forum, but didn't see anything.
As always, it is great to have a community of enthusiasts willing to help others.
Thanks in advance
For Clarity, here is a picture illustrating the spacers.
Get rid of the odd ball thin extra spacer. Put everything else as it should be crank pulley ,spacer ,PS brace etc. While using the correct tool pull the power steering pulley into alignment to solve your problem . Only move just enough to achieve alignment. With all of the other parts correct that is the only adjustable part.
Thanks Bob!
The Snap-on site does not list sizes for their power steering hub puller -- just general things like Ford, Chrysler, etc.
However, more than one puller says it will work on Ford.
Since we have pro-restorers here, perhaps they know which one works on the large 67 1 3/8 Shelby hub:
CJ113
CJ117C
CJ124A
I know what you're thinking.
Call Snap-on.
I did but they didn't know either. Other than the CJ124A is larger.
Acting on a hunch I bought a CJ124 (no A) from eBay and it just fits.
The aluminum bracket that the pump mounts to is usually bolted up against a cast iron bracket that supports the AC pump. On applications without AC, you need a spacer to make up for the thickness of that cast iron bracket. Which direction are you off? Does the pulley need to move out from the engine or back? Which aluminum bracket do you have? Does it have a "C7" part number or "C8"?
The OP noted he has a C7 bracket.
Since he has to move the pump toward front of car, that indicates pulley is too far back (on pump shaft).
Here is what I have. However, we have no idea where your pump internals came from. And it doesn't matter.
Assemble this with the stock large spacer, thin bracket at rear and use a puller to get correct belt alignment.
His post mentions nothing about the aluminum bracket. He states he has a "C7" crank pulley. He may, though, in fact have the "C7" bracket if the PS pulley is too far back. The "C8" bracket would put the PS pump pulley farther forward. A pic of his pulley alignment would help.
Just as a point of clarification.
My belts are aligned with both the alternator as well as the P/S pump.
See pictures named Belt 1 & Belt 2.
I cannot find a part number on the aluminum bracket.
See picture named Belt 3
However. There is a 2nd spacer between the aluminum P/S bracket and the head.
See picture named Belt 4
The shaft on the P/S pump is just about flush with the outside hole of the pulley.
I have not tried to pull the pulley further out on the shaft and then removing the extra spacer.

The PS pump bracket that came on all 67 Shelby's as well as Mustangs was the C7AA marked bracket.It would not be too far back but just right. Why don't you post a picture showing the difference in mounting between the C7AA marked bracket and the C8 version . I only have C7AA marked brackets otherwise I would do it. I would like to see that.
Does any of this help?
JD... I would like to nominate you, as our in house personal illustrator for your awesome pictures and illustrations. Easy to understand these minute details and variations in parts, and your passion to convey them. Keep it up my friend. ;)

That is only for the C7AA bracket. I know JD knows this but for others ,small letters/numbers =TRW ,large letters/numbers =Ford Thompson. I want to read more about the different alignment Scode67FB says that a C8 marked bracket has compared to the C7 bracket.
I'll try to get the "C8" bracket out tomorrow and post pics of it for comparison. It's actually off a 68 429 engine, but it looks identical to the "C7" bracket (except for the additional depth). The same PS pump will mount to it, and it almost looks like it could be used and line up correctly without the spacer. I don't know if it was used on anything other than the 429. I don't this bracket is the issue the OP is having If it were, the PS pulley would be sticking out too far.
One thing, though from his pics, shouldn't he have a two-groove water pump pulley and have the PS belt go over the water pump to the crank? I've never seen a setup that only ran between the PS pump and the crank.

(Bob has forgotten more than I'll ever know on these cars!)
Also, for those wanting to match bracket, as Bob has pointed out, to the pump...
Ford Thompson = the Teal-ish metallic blue power steering pumps and
TRW = the Black power steering pumps.
The tag on the back of the pump in the middle line has either a "F" for the Ford Thompson or (IIRC) a "W" for the Black TRW pumps.
Wow, thanks for the pictures
My bracket does not have a casting 'hump'.
The lettering is quite small and has the following
Top Line: very small and faint '67'
Bottom Line: DD 53001-1
Thanks
Randy
Randy, looking at your photos it appears that you (maybe) missing a stamped sheet metal part that goes on the back of the pump and is captured on the stud and sandwiches between the back of the bracket and the correct spacer, see attached image and then look at the left and center images in the second photo of reply #11 on the first page of this thread, also in reply #15 (this page) it is shown captured by the large nut center on the back.
Yes, I have that piece thanks to Bob G.
Just haven't put it on yet. Even the thickness of that bracket won't take up for the 1/4" spacer.
And so for clarification would 1967 Shelby #23 have used the power steering mounting bracket with the large C7 letters or small?
And here are the numbers on my 2 pulleys.

It could have ether. A large percentage of early cars had the small letter bracket and TRW pumps.
Finally found the C7 numbers on my P/S Pump Bracket. They were hidden by the black bracket. Has the C7 in small numbers. So I guess it is the correct one.
Back to being stumped.

You're right. I misread that sentence.
The 60-68 MPC makes no note of a difference between 67 and 68 aluminum p/s pump brackets. But we all know how accurate that can be. I have three 67 versions (small and large script) of the C7AA-A version. I parted out a few 68s but i have nothing with a 68 part number.
I'd be interested in a dimension on the long bolt portion of a 68 aluminum version.
[I have measured the large and small letter versions and I find no length difference at the long bolt area of the bracket.]

. For his application of 67 GT350 the single sheave pulley is correct.
