after 4 months of being on jackstands making the '89 caprice rear end fit, I finally drove it around the block tonight. I would have driven it more but I don't have ins. on it and I didn't bleed the brakes as well as I thought I did.oh well there is only a few tinkering left in it. I really have to change my tune since there is such a huge gap between 2.56 and 3.73.it's now 1:30 am so I'm going to sleep.
