NP435 and T-19

[zac]

My '70 K10 Suburban is driven occasionally and usually on the highway. It will not be driven in bad winter conditions because I don't want it rotting away (like my last burb). My '79 K20 Camper Special takes care of all the dirty work. The sm465 is a great trans, but it's a pain in the burb considering how I use it. I briefly had a '76 Scout 2wd (?) which I hated. But it had a good-running 304 with a close ratio T-19. It was a great setup for a street driven truck with a small V8. The sychronized 1st without the granny was great. Granny in my burb NEVER gets used. I still have the T-19, how about swapping that into a 4wd burb? If it's not possible or too much of a pain, how about the gm version of the np435? I know it is similar, and came in 4wd versions. But the published ratios I've seen seem a little less logical than the T-19. Any information that can point me in the right direction or any experience you can share would be appreciated.

GM only used the NP 435 on 4X2 trucks. You would have to use a divorced transfer case like an older Ford or Dodge, or maybe it would be possible to use a later Dodge NP 435/integral transfer case and install the GM input shaft and bearing retainer if that is possible. Finding GM style NP435's is tough. As for the T-19, you would have to use an aftermarket bell housing. How about an NV 4500? Would be costly, but it is probably the best way to go.

Yeah, I suppose the NV 4500 would be best, except for the cost, like you said, and the fact that I don't really need overdrive with my 3.08's. I'll save that link. You never know...
