Update on rear end and suspension rebuild..
Gary Ramadei is rebuilding the 78 rear end that Ed Johnson donated to the project. Here are some pictures of his inspection and comments.
"Looks like this came out of a 79 vette. The gear date is Aug 1978, maybe it made it into a later 78? Doesn't matter the 78 & 79's were ok but did have some areas that were weak. The clutches, ring gear bolts, and axles were bad and this one is typical as it has all those bad parts. They are not going to be reused though, I will use the best parts and that will make a difference. The axles had 065-070 endplay and were mushroomed over. These are just good for cores now. There were no broken snowflake clutches so that means this diff wasn't beat on much, otherwise they would be broken. The ring gear bolts used from 77-79 were junk. They stopped using lock washers and the bolts didn't have the shoulders like the older ones did. I will use ARP bolts, you can see them next to each other in the pictures."
