Spindle ID as nothing fits?

9" drum brake spindles?

You need some 73-76 A body or FMJ spindles from what the instructions show.

I have a pair of FMJ spindles for a bunch less than that one ad if you are interested.

PM sent.

I need some educating, what are FMJ sindles?
Can they be used with the control arms I have?
Are they drop spindles?

Cheers
