Ok I finally got ENOUGH!!!

All that clair.davis said: ditto!

I removed and capped the zerk fitting on the uca, otherwise, no issues on the front with 17x8 cobras. on the back, with A body 8 3/4 rear, I JUST cleared the leafs with a 5/16 spcer but it looked kinda funny and the spacers were cheapo junk. since I have longer studs I was worried that I wouldn't be able to find spacers thicker than 1/2" without the extra studs installed.

finally found these:

I'm using the 3/4" spacers until I can get a B body rear. I'm just not comfortable using anything thicker, even temporarily.
