Is there any "rule of thumb" to follow when buying hardware especially the more or less invisible kind? The first things I find I need are the 3892755 speednuts that hold the forward rear spring mounts in place. For something like that I wouldnt want to reuse original and care more for a quality product then a dead on original part.
I came up with some brake parts while rooting through my stuff. 5463565L & 5463566R brake backing plates and a 5460348 brake master cylinder and Delco Moraine power booster. Where would I look to see what these came off of? They look like someone reconditioned them. I am thinking they have to be Chevelle or A body parts.
