Eyee.... don't remind me. Lately I'm finding out more ways than one, especically with my boy, kid's gettin big and gettin pretty smart too!

That link you sent me was great info but is there nay way of knowing which of those GM cars that was 58" wide used the 8.5" ring gear 10 bolt? Rumor has it, that ifn' I'm gonna run a 10-bolt the 8.5" ring gear one is the ONLY one to go with. Any truth to that too?

I guess if anything else, I'll just have to do it the old fashioned way and dive under each and every one and see what it is.
