4 speed in 84 Silverado
 

So is the sm465 the only 4 speed offered in these trucks, trying to figure out what i have. I'm almost positive i have the np205 t-case. As i understand these are both pretty badass pieces? I'll add a pic of my sweet ride that i pretty much stole for 1,200 plus my 91 firebird formula w/ no engine

no one?

Is your t-case cast iron? If so it could be a 205.Most 81+ trucks had 208 alluminum t-case's.Most all Chevy 4spd's from 70'/71'-89' were sm465's to my knowledge.I haven't ever seen anything else but have heard of others.How much lift do you have and what size tires?

how many pto covers? 2=sm465, 1=np435
I believe the only factory 205s were in the 1 tons and had slip yokes(in the 80s) What's the tc shift pattern? tranny shift pattern? the sm465 first is left and forward.

Yeah,I forgot to mention that.77'-87' and 88'-91' OBS 1ton's all had 205's except CUCV's.Some were slip yoke,some were not. We have 4 1ton t-case's{86+} and all are fixed yoke.

Is this a K/30?They`re the only ones with NP205s.

That truck would have come with a 465/208.

465 with 32 spline output shaft and a 208. The same as my 86 shortbed.
Later Willis

I have seen a limmited number of those trucks with a smaller 4 speed w/o granny gear and 4th is an OD real rare though

In a 4WD?
