Only 3 leaves in the rear leaf springs?

Bob, do we have any info as to when (either by date or car#) the change from 5RS68 to S9MS occurred?

Hey 69 GT350 Vert, could you possibly get measurements of you middle 2 springs to see how they compare to the S9MS ones that Bob has measurements for to see if they are similar?

Anyone else out there with the 5RS68 springs, could you post your car # and build date if you have it to add to our info?

THANKS!

Hey Doug, I see you have an early 69 car. Did you ever look for markings on your leaf springs?

Hey 69 GT350 Vert, what number is your car? I am trying to figure out which ones should be on my car. I bought it back in 86 while I was still living at home and tore it apart in 88 before cell phone cameras (I think) and had no idea that they were different than a stock Mustang spring. For a number of years after that some of the parts of the car were there and some were here until I got my garage built here. I don't know what happened to them as I was also running a small block Maverick back then and don't know if my dad figured they were scrap or what but unfortunately he was not a big fan of my car addiction. Anyway, just trying to figure out which ones I should have if anyone is sucessfull in getting an accurate copy made. Thanks, Dennis

FPA ++++++  Stan makes a great product. Every set is custom made (which is why no prices are listed) and I think he's done some for every combination out there. They're definitely not cheap but everyone I know that has used them has been more than satisfied. Mine are down in the basement waiting for the car to return from Paint Prison. Mine were for a 351 car and IIRC I was right around $1400 with the Black Ice powder coating, a drop bracket and shipping. Usually 4 - 6 weeks, a little longer over the winter when everyone is building.

Bob --- sorry, maybe I mis-phrased my question as I did not know if anyone had the measurements for the Boss 302 springs and was just musing which springs were made first.

Jeff --- what is the early build date of your Boss

Ed --- looks like Shelbymann1970 also has a SMS lower leaf that he is using with his person to reproduce.

Gary -- keep us up to date with your endeavor. I"m sure a lot of us would be interested.

To all --- thanks to everyone for their input. I have seen this topic come up a few times over the years and just seems to loose steam for whatever reason. Hopefully this time a solution can be found.

I know I lack a lot of the knowledge of most on here but just trying to participate and help find answers

Thank you all!.

Can't find the chart I was looking for on the General Spring site but their listings do show the same industry #42-503 for the GT350/500 as the Spring Research chart. General is not showing a listing for the Boss 302.

There was similar information on those springs on a chart from General Spring in iirc Kansa City MO. I'll have to go back and look for it.
In reference to reply #30, another question, were the 69 Boss 302s in production yet when Shelby ordered the Mach 1s used to start building the Shelbys? Maybe B2 springs were not in production yet, but specs were known. Since both cars have a similar squat, it would seem that it could be the same spring.

Would be interesting to see a side by side comparison of the Mach 1 spring that the car left the factory with and the spring A.O. Smith put in as far as length of the individual leaves. We know the top is the same and the bottom is different but what about the other two and did it retain the 550# rating.

Also, was ford making their own springs back then or using an outside vendor? If made in-house, did they also supply the Shelby spring to A.O. Smith or did Smith use their own vendor. Is it JRS spring that is also located in Michigan? More questions than answers.

Kinda sad to see them all just sitting there.

Was that your original harness or a new one? Thanks, Dennis

What kind of material did you use for the clips? Thanks.

Have the end cap sent to Dave Topper. It will come back looking like new. He did my headlight buckets. Look like they just came out of the box.

Hi Mike, my Marti report does not show the Park light but my build sheet (repop not original) shows a V under the Visibility/Convenience box. Would have to find out what the V stands for but my understanding was the Park light was part of the Convenience group but not 100% certain of that.

I thought the early cars only had the Park light and the Belts light came later. That's the way mine is (Jan 8th). Did you check you parking brake mechanism to see if the switch is there for the Park light?
