Does anyone know if the dimesions are the same between the SM465/NP205 and the TH350/NP205? I am getting ready to purchase the SM465/NP205 and pull my TH350/NP205. What else do I need to cosider, I am getting everything out of a 1970 Blazer and it is going in a 1972 Blazer. I will be getting shifters, linkages, pedals, bellhousing, clutch, flywheel and of course SM465/NP205, the seller said he just rebuilt this setup. I just purchased custom Drive shafts and need to know if it will effect them. My 1972 Blazer has 4" front springs with Hills extended shackles and the rear has 6" springs the springs are Rough Country. I will also be ordering all the greasable bushings from ORD. Is anyone running with a custom built Dana 60 Rear, I am looking at having one put together for the rear of my Blazer and wondered who has the best setup out there. Thanks for your help!
