The retaining clip I am referring to is to retain the speedometer drive gear on the cable. The number for it is FMC C1DZ17292A, and Ford Country in the Valley Auto Mall always has them. I use the 19 tooth pink drive gear for a 3:54 rear-geared car, and thats FMC C0DZ17271B, again Ford Country.

The o-ring is just a generic part. If you take the cable to Autozone, Napa, etc they can easily get you one for probably less than a buck.

I'm not sure why the retaining clip on the cable wouldn't fit, they always have for me. Just to make sure we're talkin the same thing, its a crows foot that uses a 1/4-20 bolt screwed into the tail-shaft??
