sm 465

Can I use any year sm465 to mate to my 71 np205 transfercase as long as I have the adapter? When they say 10 spline and 32 spline, is that the front input shaft or rear?

10 spline rear output was most common in the 4wd. Later model trucks had the 32 spline rear output. So yeah, just about any 4wd up to '85 or 86 is what you'll be looking for

I used a Sachs clutch in mine. That is after the center hub broke on my Centerforce (no abuse or dropping the clutch). The clutch has held up great for over 15 years now with a big block and some towing.

Really it depends on the engine. A 3500 would probably be ok with a stock small block and conservative driving. I have a 4500 with a mild 454 and am still cautious with it. I still think that a 465 is a stronger trans. No proof of that but just a feeling after driving both.

Same here. Sachs. Upon opening the box though, I saw the Valeo stamping on the PP and clutch. Has held up fine with the 396 and now the 454 and has to be going on 5 years or so. Lots of towing 7-8k, once in a while 10k+. I do hammer the throttle occasionally and it has never slipped that I can tell. Way cheaper than a CF.

Nonstop, good to see you here a little more recently!
