thanks....hard part of going with FMJ/junkyard sourced parts is the fact that they were last made 34 years ago, so not many in yards anymore....

car is a slant6, manual everything, plan on keeping it, maybe mild upgrades to the 6 (thinking 2bbl, maybe a little cam, exhaust either headers or dutra duals, probably milling and porting the head). when I redo the suspension I'd like to get a bit firmer than the stock slant 6 tbars, but am not looking for corner carving, just competent....was looking at the Mancini racing XHD springs for the back https://www.manciniracing.com/maaexhedules1.html for the front, stock BB t-bars (.890?) if I can find them? I see firm feel sells both .880's and .940's....I'm concerned anything bigger than that and ride will get too harsh, especially if I decide to go with 17" rims....
