A-body LCA 67-72 vs 73-76 differences?

Junkyardhero, that is great information, thank you. I will take all of it into consideration. I'd prefer to install a factory style setup, which is exactly why I'm trying to learn these differences. I understand your point about location not making a significant difference. Guess it was just my OCD kicking in.

DionR, that's some good info on the Hotchkis stuff too.

You guys have brought me up to speed very quickly and I appreciate it. Thank you all.
