I was considering doing a set of 3.55's for a Christmas present, but after looking around it was much cheaper to just find a solid rear end with the right gearset in it already since I was going to have to pay someone to put the gears in. I ran across a 3.73 rear end locally that was rebuilt about 10,000 miles ago. New FRMS gearset, new FRMS trac-lok and all new bearings for $200. The guy is trying to clear out his storage unit so he can start on a new project. I talked him down to $175 and brought it home yesterday. He's also throwing in the speedo gear for 3.73's at no cost.
I wasn't planning on 3.73's, I was planning on 3.55's. About 13-14 years ago I drove a notch with 3.73's for a couple weeks. While at the time I thought I was the sh**, looking back on it I remember them feeling like really short gears. But, I figured this was a pretty good deal to pass up, and if I decide I don't like them I could probably turn around and sell the rear end pretty easily. All I'm out is my time, but with this being a project car I'm OK with that.
I popped the cover off this morning to verify that pinion gear was 3.73 again and just double check everything again. I'll end up replacing the fluid before I install it in the car along with the axle seals.
I pulled the rear out the garage and got it all cleaned up. You can see all of the dirt on the driveway.
I removed the brake line and now I'm contemplating covering up the ends and pinon flange and putting a couple coats of primer on this following by a flat or satin black paint, just to clean it up a bit more. Thoughts? I know it's under the car and you'll never see it, but while I've got it out I figured I might as well freshen it up, no? Any tips/tricks/etc.?
I been following this guy for awhile in his restoration. He had a post towards the middle/bottom of the page where he painted his.
