ive got a 1955 chevy pickup. i am looking to replace the rear axle. i was wondering if anyone knew of a year that chevrolet made an axle that is the same width as the one currently in my pickup. thanks for any answers. sorry for not specifying, the truck in question is a second series pickup. do any of these vehicles have posi-trac? what size is the replacement rear end? thanks again | | | | | Joined: Feb 2001 Posts: 4,109 'Bolter | | 'Bolter Joined: Feb 2001 Posts: 4,109 | if it is a 55 first series a nova has worked well for me. be sure and check the gear ratio. 3.11 or higher. the 55 first looked like the 47 thru 54 the 55 second looked totaly different. hope this helps. ron

[img] http://img.photobucket.com/albums/v374/55chevy/55Camp2.jpg[/img] I just picked up a 1977 camaro z-28 rear end. It runs 5 lugs and has drum brakes. Has a 3:42 gear ratio and will mount nicely. I plan on converting to 5 lug disc brakes up front later. This rear end only has 67,000 miles and came off a running and driving car. If you want to go with a six lug look try the 73-87 K-5 blazer. Hope this helps, Chris
