Help req'd with p/n for rearend cover
I have a 1988 Formula 350(ws6) with the 3:27 gearing. Want to get a new cover to detail but need to know which ring gear I have--7.75 or 7.6 in order to order. Also; to order a corvette servo in total kit form thru GM dealership; would there be a p/n known as the dealership I frequent is having problems finding the above 2 requests. Any help in this matter would be greatly appreciated.

Sounds like you have the 7.75" rear. Count the bolts on the cover; if there's 9 it's a {drum roll please} 9-bolt which is the 7.75", if there's 10 it's the 7½" 10-bolt.

If that cover isn't beat all to hell, just sandblast it and repaint it. I have a pic of mine in this forum somewhere but search is down so I can't pull it up.
