I got a 4speed manual (GM 3901127 stamped in it) mated to a Dana 318 tcase?? I picked this up from JeepSteel thinking it was a Dana 300, but it was covered in so much gunk i couldn't really tell. Either way it's a 4 speed GM tranny, mated with what looks to be a factory adapter to a Dana 318 (are the first numbers on the case under the DANA logo) transfer case. It's got a funky shifter thing for the 4x4, it's a curved S bar, that comes behind the transmission (in front of tcase) but the tcase shifter ends up to the LEFT of the transmission shifter....and it's a twin shift rod tcase, similar to a Dana 20 or 300. But it's got this funky box thingy on the 4x4, that allows you to have a LEFT 4 hi and 4 low, and a RIGHT 4 hi and 4 low....i'm stumped. I found some "dana identity" websites, but non of them had this listed...

i'm positive that little box thing is wrong...not sure how...but nothing from the factory would ever (in my mind) come with front wheel only....they just didn't do it...people mod it for that sometimes...maybe it's been modded...

I'll snap some photos tonight, i'm POSITIVE it's not anything NP...it's Dana...and small...tranny shop told me it was absolutely an SM465 4 speed GM....so that's cool. I need to seperate them and see what the spline count is. Then sell it, but i think i need to sell it as a combo because otherwise who's going to want this thing? i mean i think the adapter is pretty rare maybe...i'm stumped.

coloradok5.com here i come!

Well it's an SM465 married to a Dana20 FOR SALE
Found this:


1969
First generation
1969 Blazer
Also called GMC K5 Jimmy
Production 1969–1972
Body style(s) 2-door SUV
Engine(s) 250 in³ Straight-6
292 in³ Straight-6
307 in³ Small-block V8
350 in³ Small-block V8
Transmission(s) 3-speed automatic
4-speed manual

The original K5 was a short wheelbase truck. It was available in 1969 as 4-wheel drive only; in 1970, a two-wheel-drive model was offered. There were four choices for power plants: the 250 in straight-6, the 292 straight-6, the 307 V8, and the 350 V8.

The Blazer was designed and marketed to compete with International Harvester Scout and the Ford Bronco. Both of these were originally aimed at the short Jeep CJ series, which were much smaller than other trucks. The great innovation of the Blazer was to simply offer a shortened pickup truck, which both increased interior space, and lowered the cost of production with a shared platform. The Blazer quickly became popular. For the first time, it married the off-road capabilities of the Scout with the "luxury" features like air conditioning and automatic transmissions routinely available on pickup trucks. By 1970, the Blazer was already outselling both of its older rivals. Ford, Dodge, and even Jeep would counter with similar shortened pickups, with the Ford Bronco, Dodge Ramcharger and Jeep Cherokee.

The two-wheel drive version had independent front suspension, and rear trailing arms, both with coil springs. The four-wheel drive version had a solid front axle and used leaf springs front and rear. Both versions used drum brakes front and rear until 1971, when the entire GM light truck line got standard front disks, while retaining drums in the rear.

There was also a choice between a three-speed automatic transmission Turbo Hydromatic (TH350), a three-speed manual transmission, and a four-speed Saginaw Muncie (SM465) manual transmission. Two transfer cases were offered: the Dana 20, available only with the manual transmission, or the NP-205, available with either transmission.

Engines:

* 4.1 L (250 in³) 250 I6 (1969-1984)
* 4.8 L (292 in³) 292 I6 (1970-1971)
* 5.0 L (307 in³) 307 V8 (1969-1973)
* 5.7 L (350 in³) 350 V8 (1969-1991)

Transfer cases:

* Dana 20 - gear driven part-time four-wheel drive
* NP-205 - gear driven part-time four-wheel drive
