    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!

    don't have dimentions for ya, but i know that sm465 is a very short tranny, my 77 reg. bed has sm465/np205 and it has factory two piece drive shaft, short short set up. i would be very surprised if you didn't have to modify your drive shafts. (but than again...)

    The total length is the same, so it is a complte bolt in. You will even use the same drivelines. I did the opposite of what you are doing ten years ago on my 73. I had no problems.

    One more thing, you will need a bracket for the clutch z-bar that bolts to your frame.

    The above statement about the 465 being the shortest setup is true. Especially when the front axle is a D60 and the 465 is employed, the front shaft is the shortest of all the combinations.

    Thanks for the help with this! I am currently deployed to Okinawa, Japan, I am an active duty Marine. I am going to purchase this setup from a member on the site. I have a 1970 LT1 Block that I just built for the Blazer and after installing it I could spin all 4 tires in 4 Hi so I figure the TH350 wont stand a snowballs chance in Hell. I am hoping that the SM465 will have a better chance for survival. I dont abuse it in hard rocks all the time, except when I go to the San Bernadino Mnts. I most use it in sand and as daily transportation. Thanks again!
