Re: Project Screamer - '72 GMC K2500 + DD 4-53T

Very nice work and I love the all spicer pieces going in the drive line. I wouldn't mind having a lathe so I could build my own too.

I don't have a lathe either, so this will be an experiment. I've always wanted to try making my own shafts, all I have to lose is some 2" tubing.

I will have to take it to a driveline shop for balancing at any rate. If I can't achieve acceptable runout myself, I will cut and fit everything and have them true,weld and balance the shaft.

Re: Project Screamer - '72 GMC K2500 + DD 4-53T

Cross Member Part 2/Rear Transmission Support:

As I designed the cross member, two things determined the height. 1) I needed adequate clearance between the bottom of the transmission and the top of the isolator bolt and 2) I wanted the front drive shaft to be level from the front of the transfer case to the center bearing. It turns out that the front drive shaft was the determining factor.

I decided to make the cross member of 1/4" plate. It is 1" thick and 8" deep. The depth allowed me to put the transmission support where I wanted it and allowed the center yoke of the drive shaft to fit around the transmission.

Here's the first mock-up of the cross member:

I made the rear support for the transmission in a wishbone shape so that I could incorporate all three support studs on the rear of the transmission. Here it is with the standoffs tacked in:

I used a single poly isolator, the same one that I used for the motor mounts, to isolate the rear support from the cross member. Here they are assembled on the work bench:

I'll work on the front drive shaft next.

Nice work on the support and cross member.

Front drive shaft - done! Only 997 items left on the work list.

I fabricated the front drive shaft. It fits neatly around the transmission.

I have some things that I need to resolve while the cab is off of the chassis. One issue is the routing of the parking brake cable.

Re: Project Screamer - '72 GMC K2500 + DD 4-53T

Very nice work! I feel your pain on the 997 things left to do. A restoration is bad enough, then throw a conversion in there. Yeah, it is cool when it's done but boy they take a while to do right.
