Help! Calling All Spindles!!

An Aerospace kit is better priced than that one! Part of the reason for the big price tag is the billet AMC hub though. Aerospace makes a billet hub too as far as I remember... or they may have found a hub that fits the AMC spindle and made up any difference with the caliper mount (but I don't think so!).  There are some guys in one of the Texas AMC clubs running Mustang II spindles, but the offset of the rotor is different and they had to make spacers or custom brackets (don't recall which) to mount the calipers. I don't recall any details, but I think it's the small bearing spindle (drum brake/79-83 disc) that the MII bearings work on. I don't recall if a spacer or anything like that was needed on the spindle.

That is great! I am awaiting the results. Sure wish I could get my car built by the prototype process some of you lucky individuals are participating in! LOL!

Needafasteramx is correct -- distance "M" is the same depending on the bearing set used. There were two bearing sets -- for all practical purposes "small" (A2/A6) and "large"(A16/A17). ALL AMCs use one of those two bearing sets -- period.

All drum and the 65-70 Bendix discs used the small bearing set. I don't recall about the K-H discs, but the 75-76 (through 78 for Matador) "Big Bendix" 3.1" piston disc brakes used the big bearing set. Oh yeah, 77-78 small cars used the big bearings with the small Bendix 2.6" calipers -- those are odd balls! 79-83 small cars use the small spindle.

There is a difference in the base height of the spindles. Richard has it backwards -- the disc spindles are thicker than drum. Has to do with the offset of the caliper and clearing the steering knuckle, not the addition of the caliper mounting bracket (which would be the logical conclusion!).

There are several base heights used over the years to change the offset of the rotor and track of the front end. Too many minor changes there to document. Part numbers don't help -- sometimes there is just a change of part number for no apparent reason, probably just to streamline the part number system on occasion.

TomJ did some research a while back. Though it's a bit inconclusive, it does provide a general overview. See http://wps.com/AMC/spindles.html

I do have a set of drum & 4 piston spindles in storage attached to the knuckles along with the rotors/drums still attached. Would take time to dig them out and pull apart for measurements if needed.   See we have 2 of them so far and it will always be the one we need to use is not the one we have! I say when they offer a “kit” and that kit uses 1 of the AMC spindles they should also offer one just in case as this is what the down fall seams to be with any “kit” for AMC. Once we get measurements from a drum spindle we will then know if any of them might work with a Wilwood hub & hat. Dave ----
