I just bought a 1950 Chevrolet 3600 pickup. It has a front suspension from what I am told is an AMC Pacer. I will post pics later so the more AMC knowledgeable people can point me in the right direction.
It has drum brakes. I am trying to get to disc brakes without cutting all the suspension out and starting over. 1st question: Are there any numbers stamped on the drums/hub assembly to help identify year/model? 2nd question: Is there a disc brake spindle that will bolt into place to get away from the drum brakes? Thanks for any and all help. I will be back with pictures later. Scott |

Gi, I saw your post on the other topic. I'm a long time amcer but know even less about pacers then others.
But the "numbers matching" thing is a GM invention. No concept here. Keep in mind how small AMC was. Ford made more Model Ts, than AMC made cars, all models combined, in it's 30 years. They were a very small company. The best news about that is they reused the same parts all over. There's wild interchange across the board -- with brhe exception of the Pacer, the uniqueness of which probably lead to their demise. There are terminology diffs too: what GM calls a spindle, in AMC land is composed of steering knuckle, the spindle proper, and steering arm, held together with four bolts. This adds weight (slight) and manufacturing cost and labor cost, but it's great for diy and modifications!! AMC did a lot of truly great frugal engineering. The amc spindle comes in a couple different heights, and dates back to 1950. An 80s? version had a larger bearing. For the rest there are short and tall bases, about 1/4" height difference, these interchange sorry of, but determine brake in/out position. You can shim the short one out to tall height. But I'm not sure anyone can tell you solidly which height came on which cars, even today. Gotta measure and ask.

I would look for a stock Pacer disc set up, they use a big rotor and caliper. I don't have my parts books with me to look up the spindles. Fyi the rack & pinion is GM and the seals leak more than most.
This a VERY good front suspension for any vehicle, much better than the pinto style. Ron.

It's a good suspension I agree, except for availability of parts.
