1. Spindles

2. maybe newer stuff?

3. 68 B Body

4. also 68 B body?

I'm assuming you dont have any A or B brakes on a car that you can measure. You might get a distance from a horizontle line thru the CL of the lower bolt holes in the spindle up to the top hole & someone might be able to compare that # to what they have (just thinking out loud here).

I am pretty sure the disc brake set ups for 67,68 and 69 B-bodies was the Bendix four piston caliper setup. This set up is slightly larger than the Kelsey Hayes four piston setup that I think was available on A-body disc brake option in 69. I think that same K-H setup was also on Mustangs of that era. In 70, I think Chrysler used the single piston caliper design you show in your pictures across the models.

69 and earlier B body did not use caliper bracket, and as stated they where Bendix 4 piston. 70-72 B&E Body used the same floating KH single caliper with bracket. But those calipers do not have the correct casting #. What is the # on the adapters?

Last picture looks like fmj stuff to me.

This above. Small mouth '73-'89 Slider calipers and brackets in the together pic. The calipers brackets and calipers in the seperate pics are Kelsey Hayes pin type. read the above to figure out what ones you have.

If the inner bearing journal diameter measures 1.25", the first and second pictures are '70-'72 B/E body stuff.

The last picture is '80 and newer F/M/J body.
