Curious to see how many on this forum with 66 G.T. 350 cars have overrider rubber boots versus th fiberglass boxes or are they missing on your car. I have none at the moment but doing the forensics seems to point to the rubber boots judging by the rivet holes and also where one rivet still remains as a holdover from the restoration. It looks like the boots had three rivet holes. I have an inquiry out on my car to someone who is definitely in the know and we shall see. My understanding, subject to correction of course, is that the boot type solution came from Ford's Heavy Truck parts bin and it is actually a brake lever boot with a parts number P/N C7TZ-2A713-C, Brake Lever Boot. See two photos attached.
i have installed the boots in the past but do not think they were ever done at shelby ...... but they seal much better
On reliable authority i.e.the prior owner, mine had the boots. I bought the ones pictured above. Not a match exactly but is as good as it will ever get.
Although I don't have the actual boot part number of the boot used on the 66 GT350's,the part number of the boots in the picture C7TZ-2A713-C are a 1967 truck part number that would not have been available in the early 1966 production time frame when the actual used part was sourced.
This is an NOS C6TZ-2A713-A park lever boot, I assume if they were used at SAI, something like this is more likely what was installed since it has a C6 part#.
843 had long rubber boots. They were square edged and had a round part where they went around the bar. They had thin (about a 3/8 wide - 1/16 ish thick) aluminum shop made flange that was pop riveted. I've tried to approximate the shape/size. In the distant past I think (from a Marque article) they were Ford big truck F600+ Ebrake handle boots. They were not available even in the late 70s - superseded by the C7 number???.
Here are a couple of shots from an early 66 with the original boots that I believe have been shared here before. Like others these were formed in a rectangle shape with crisp sharp edges on the four corners.
Hope these help

All of the info does help and thank you. No chance I will find an exact boot anymore. I am lucky to have found the C7 ones and they should work on my day two car.
Hi to all,
We found the same oval cutout floor and rivet holes in #822 AND now thanks to this group of folks, can see/picture what was originally done by S.A.I. All parts were missing. Holes sealed with silicone and the oval cutout was sealed with a metal piece siliconed in place.Installed fiberglass covers to save time and they sealed things up. Wish we had the car still,was last in Texas???
Did anyone ask Howard if he has the part number for the boot? If anybody would know it should be him

FWIW, I still have the origial boots on my car (6S817). Unfortunatly, I'm not in a poition to remove the seat assembly at this time, otherwise I'd closely examine the boots to see if I could locate a P/N.

That's what 843 had.

I restored #731 and it came with boots. I also restored #689 and it came with pieces of thick rubber with a hole in the middle for the traction bar to go through with the fiberglass cover over the bar secured to the floor with riviots.
Hey to all,
Just re read the book by Chuck Cantwell and page 105 shows the boot and the foot note mentions a shifter boot from a Ford truck....may not be from a parking brake as we thought. Most likely an
Obsolete part from Ford, somewhere or somehow it would be nice to have the original part number
To chase. My guess is in the 7200 range of Ford numbers.

Pictures seem to indicate a park brake boot.

Yes - large exit hole for tubular ebrake handle not smaller dia solid shifter rod. I tried searching 50/60s Ford big truck interior pics to no avail. Maybe some of the period sales brochures would have detailed interior shots.
I noticed in this thread several of the cars mentioned were in the #800 range. When did the change to underrides happen in '66? I thought it applied to the first 252 cars, but overrides occurred past that number range?
Thanks.
I have a NOS one of these. Unfortunately no tag on it anymore. My understanding is that it sourced from a F 450

The Registry sets the change over as being around car #920. Of course there was the change to the "kinked" bar during that period prior to the change over between upper and lower styles also
Just for grins I installed the C6TZ parking brake boot mentioned in reply #4 onto an OE traction bar (underride) I had laying around, looks to fit nicely:

That will work fine from a practical standpoint but I believe that if looking in the override hole under the car you would be able to tell the difference between that and the original one. Of course that would only make a difference if noticed in a concours judged venue.

Agreed. Guess I need clarification on one thing though...is the large OE triangular boot actually considered a parking brake handle boot? I've never seen one in person but from the photos they look too rigid to be functional for a moving handle, unlike the C6 and C7 truck boots shown in mine and Richard's photos. Regardless, it seem to be something that could be easily 3D printed.
It is very rigid
1964 F800 - no boot but same shape (size?) hole as for the Tbar.
