I have a sm465 trans. with 6,000 on rebuild, adapter,input shaft for t-case, manual column, clutch pedal ,all linkages and 4 speed high hump floor pan thing for sale. Asking $400 for everything.

hello, just to let you know, if you want to swap to a 4 speed, you will either need to get another NP205 that was originally behind a 4 speed, or get the 10 spline input shaft from a 4 speed NP205 and swap it into yours. i believe the NP205 behind an automagic had a 27 spline input shaft from the factory.

also, the SM465 and adaptor is most likely shorter than your TH350 and adaptor, and if so you will need to lengthen your rear driveshaft and shorten your front driveshaft, and you will need to move the adaptor crossmember forward, too (drilling new holes in frame = yay!

). sounds like fun, huh? I am going thru something similar right now.

I have a spare 4x4 SM465 that I would let you have, but as it turns out the rear output in mine is going bad so I will need to swap trannies in the future now too.

good luck finding what parts you need, and be careful of prices...apparently unbroken SM465/Np205 adaptors are made of solid gold or something ($$$).

EDIT: I forgot something...you could always try looking for a later model (i think its '86-'91) SM465/NP205 setup from a K/30. this setup is probably best because it has a 30 spline input shaft (vs 10 on the older setups). I also think this setup has a different adaptor that eliminates the coupler sleeve inside the adaptor itself. this is GOOD because the sleeve just creates more slop in your drivetrain, and causes unnecessary wear on parts (which is why I need to get a new tranny

but then again it did last 35 years without breaking). good luck on your swap.!

How much for the th350 np205 combo?

I just parted out a cab, it was a 4spd truck. Have a column with the pedals for a 4spd set up. I don't have any other parts, all I got was the cab.

How much for tilt column and engine. Have complete change over down to the last nut and bolt ( clutch pedal with all linkage-rod, z-bar with motor stud and frame bracket, clutch fork with throw out bearing and adustment rod to z-bar, bell housing, flywheel with same as new pressure plate and disc and all stock return springs. Also have the manual steering column and a 3 speed trans with a Dana 20 tranfer case. Got a idea--why don't we do a swap-I got everything you need for a manuel swap and you got everything I need for a auto swap (we could even swap drive shafts). I live in Knoxville, Tenn.
