New project, tranny/transfer case question. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm building a mild trail rig. It's a 67 Scout 800, 4.3/700R4, 4:10 gears, 33" tires, 5" lift, etc. The engine/ tranny is out out of a 85 Astro. I want to use an Atlas transfer case. What do I need to attach the TC to the transmission? Thanks

i would just go to the advanced adapters site..they will have every bit of info you need....

Instead of Advance Adapters, try Novak Adapters...cheaper and better quality. I believe Novak moved to Utah, so you'll have to do a web search to find them. Good luck.

Found out I need to go with a long tailshaft. The part # for the adapter is 50-9102 (I think). I know some of you have converted to the Atlas, any comments? I'll be going with the 3.8 model. I have a 100 inch wheel base, I'm still conserned with length. Don't want any surprises. Thanks
