500 trans

Hi Everyone,
I know I should know this already but asking to be sure. Did all 67 500's get the rug S 4-speeds? What would make it a S1? Much of a difference between them?
Thanks

Yes they all came with the RUG-S for the earlier ones and RUG-S1 for the later GT500´s the casting numbers are different depending on which car you have earlier or late one. Internals and ratios are the same.
