how to identify SM465/NP205

i'm going to start looking for a 465/205 combo for my C10/K10 project, and i'm wondering how do you identify a 465 and a 205?

The SM465 I believe has PTO covers on both sides, but I'm trying to remember there is another way for easy ID.

I am trying to figure out how to ID these too-I'm new to 4x4 stuff but I've had a few of these trucks(2wd)

the truck is 80 miles away so...

I'm getting a 71 or 72(not real sure but I know they are mostly the same those 2 yrs) I'm pretty sure it has the (original)205 transfer (what are the chances it could be anything else?)

the trans is a "granny" 4 speed(original) I'm told-would this be the 465?
is this a 4 speed + lower gear or a 3 speed + lower?

now for the tough decision-a part of the deal is I can swap in a TH-350 with it transfer case(from a later model truck)-or leave the current setup in--but--It has to be one or the other-the guy wants to keep one tranny/transfer setup but it doesn't matter which(but I'd have to do the swap)

I guess what it comes down to is can the newer parts possibly be as tough as the original stuff?and would it be worth the hassle?

Its a 4spd, with a 6.50-1 1st gear. Low gear is part of the friggin tranny, just like the other gears. This drives me nuts.
BUT to answer your quetstion, there are 4 total gears... Sometimes the knobs are stamped
L-1
2-3-R

but, technically its still a damned 4spd!!! LOL

MY opinion, (and Im VERY opinionated ) is keep the 4spd. Tranny and case from later truck (how much later??) will likely be an TH350/NP203. IMO, the 4spd, and the NP205 will be ALOT stronger... My friend has gone thru a few TH350s, in his truck with 36s (And they were built by a pro shop, that I KNOW knows their stuff)... Plus, the low 1st and 2nd gears help alot with big tires...My friends truck is also a total dog, with the slushbox.

If its an even newer truck, after they switched from NP203 the case will be even weaker... (READ: CRAP)

the 205 will also have 2 rods running into the case , these are the shifter rails , where the shifter connects , where as a 203 will have 2 arms that rods connect to , the three bolt plate on the back is a dead give away , now the 4 spd could also turn out to be an sm420 which are alot rarer than the 465, the 420 has a lower crawl ration , really popular with rock crawlers , my favorite tranny transfer combo is a th400 and a 205 , ive ran 465's with a big tire " 44" boggers and i didnt like it , ive had some th400s that pulled harder than any sick ive everbeen in , still got one thatll shift hard enough to break youre neck when it hits 3rd. i love that tanny , it all depends on how they are built and who bvuilds them , some people know what they are doing and some dont ,
