Idler arm problem? Please help

What about the pitman www.rareparts.com makes? Is it the same as the small block pitman or is it special for the 383? Rare parts are not dummies. They know there stuff usually.

Btw rare parts will rebuild used worn pitmans and idlers.

The pitman for a fast ratio manual will be the same as regular ratio. The ratio difference comes from the box gearing on manual A Bodies.

No, the pitman arm is not the same for a fast ratio box on a big block. The output shaft size on the fast ratio box is different than a standard box. Had to send a standard BB pitman back to Rare Parts because it didn't fit. They didn't have what I needed, Firm Feel knew exactly what I needed.
