Pic request 32 spline newer style NP205 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Critter · 05-16-2010, 11:21 PM

Can someone provide me with a few pics of the newer style NP205 with a 32 splined input shaft? This would be the one with the round mounting bolt pattern NOT the more common "Figure 8" or "racetrack". I believe this T-case would have come behind the late 80s/early 90s model 1 tons with a th400 tranny, but maybe there are more examples. Either way, a few pics of the mounting surface out of the vehicle on a bench or something would be greatly appreciated. While we are at it, feel free to include the adapter if you have it.

THANKS!

I have one but no pics. These were on the 86 to 91 1 tons with the TH400 and the 4 speeds. Same t-case, different adapters. Also have the long 32 spline input.

Hmmm...the case itself is different isn't it? I found this pic and I believe it is the 205 in question. See the round mounting surface as opposed to the the oval "racetrack" style from all the earlier models. Maybe I'm wrong, thats what I'm trying to figure out.

I agree about the year model and long input shaft details that you mentioned.

8 track went to aboot 84-85 for the auto, not sure on the stick. Then 85 if not 86 for sure cause that's where I got my 2 from, they went to the round 6 pattern like the pic you posted. They are the same for auto or stick, the difference is in the adapter. The adapter for the stick is crazy long, whereas the auto is 6" IIRC.

1991 205s had the vss as opposed to cable speedos if i remember right as well.

And the only year was 91, and only in crew cabs/cab n chassis trucks. I've seen one, and it wasn't in a junkyard or I would have it.

the 465/205 changed from the 10 spline/racetrack style to the 32 spline direct/round pattern in 84/85 is my guess, but only in the K30's. Anything lighter got the 465/208 or 465/241, which are also sort of uncommon.

The 465 with the 32 spline mainshaft had a crazy long stickout. Here is a pic:
