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

A little progress and a lot of family time...

I hope that you had a wonderful Thanksgiving. I sure did. I spent a lot of time with my family and friends. This is my favorite time of year.

I also made a little progress on my project.

I received my divorced NP-205 transfer case:



I purchased some 1-3/4" DOM tubing and had a local machine shop cut it to the correct length and bore the ID:



I mocked up the rear motor mounts:



And burned them in:





I flipped the chassis and welded the bottom side of the front and rear motor mounts. Before I could flip the chassis, I had to remove the axles. This took a lot longer than I had expected because the bolts had rusted solid to the sleeves inside the bushings. When I reassemble them, I will be liberally coating the entire bolt and sleeve with anti-seize lubricant!

Next step - cut and install the boxing plates and install the spring bushings so I can make the chassis a roller again.

More to come...

Really interested how you make this work. Awesome build for sure. How did you get the 205 and what are your plans to make it work?

I purchased the NP-205 on eBay. Just search for "divorced NP-205" and you should find several for sale.

I will end up with 3 custom drive shafts. The one that connects the transmission to the transfer case will be as short as possible and odd because the output yoke of the RT6610 is huge (1710) and the input of the transfer case is normal size.

Once I get the transmission to T-case shaft, I will fab a custom crossmember to support the T-case. Then I will have the other two shafts made. The front shaft will be the long one in this case. It may be long enough to need a center bearing.

Stay tuned and you will see it come together.

It's a roller!

I finally had some quality time to work on the truck. I fabricated the boxing plates for the rear motor mounts, welded them in and then re-attached the axles. I now have a rolling chassis again.

Here's the right side boxing plate welded in:



Here's the boxing plate with the axle installed:



Here's the rolling chassis:



Merry Christmas everyone!
