For a followup, I went ahead and fabbed some upper control arms to fit when the axle was rolled for the proper pinion angle. They were about an inch shorter than the Chevy arms. But with them installed the shocks now fit. And i have no binding in travel from bumpers hitting to hanging on shocks. Mat...

Thanks for the reply! Lots of great information. If I fabricate offset upper arms to fit into the bushings at each end, in the loaded position, do you expect the axle assembly will get into a bind before it will get enough travel? I thought I'd make two links out of 1/2" rod before I fabricate ...

Does the assembly I have have much value for resale?

OK, thanks for the information. I guess I need to start looking for a rear end. It doesn't really look too wide for the car, but the mounts are sure off. Would the carrier bolt into a correct rear housing? Are the top lugs the only ones in the wrong location? Or are the lower attachments wrong too?

OK, got a few more pictures, hope these help. The axle is oriented so the pinion angle is right in these photos. The upper arms are disconnected from the axle only, so you can see the alignment offset. The lower arms seem to fit pretty good, to me.

Casting number for the pumpkin was in my post, 1235198. I can't find it referenced anywhere. Lower arms are boxed, but it looks like the axle has had no modifications, and things don't seem to fit. The symptom was a broken transmission tailshaft housing. I don't know if the excessive rear u-joint an...

Hi! I have a 72 Chevelle, small block SS VIN, and it has a 454, with a ten bold rear end with 410 gears. The rear end does not seem to fit well in the car. It looks like i will have to shorten the upper trailing arms to 9-1/8 inches to get the pinion rolled down to get good driveline alignment. I've...
