Lower A-arm bolt confusion

[Steve L.]

I'm re-assembling the lower A-arms and have both the original bolts, A-arm to frame, and Dr Rebuilds version.

Fronts
Docs. 1-1/2 inch long, yellow chromate------original 1 -5/8,blk phos.

Back
Docs 2-3/4"long, ylw chromate,splt wshr -----original 2-1/8,serrated wshr

Paragon's catalog also shows 1-1/2'long for the fronts and doesn't show anything for the back.

Doc's fronts actuall look short when assembled and the back's look really long.

Why this discrepancy?
I'm thinking of re-using the originals and returning the new ones.

This is for a 73 coupe

I'd put the originals back. The replacements dont have the period correct headmarkings. There were no yellow dichromate bolts on these cars. And it's a safety issiue with the short front bolts.

I was wondering that as well since the front bolts don't go right thru the nut plate.
