Length of SM465 and Tcase adapter?

[D13]

I looked and 'think' I found the answer but wanted to check with people who know. I'm trying to find the length of an SM465 and its T-case adapter, preferably to an NP208C in a square body. Trying to figure out if my A833, out of I think an 1982 K10, 32 spline output to an NP208C, will swap for a 465 with similar output, without getting into drive shafts etc. Neither of us have the 465/208 combo to measure.

What I've come up with is the 465 plus adapter is 19 1/2". Measuring my A833 plus adapter I get 20 1/2". My assumption is that both bell housings are the same length, as my A833 bell is double drilled for both types of trans patterns. Looking at it the another way, the A833 is 26 3/4" engine face to t-case face, and 24 1/2" engine face to trans mount center line.

So is seems the tcase would sit 1" further rearward, needing new holes but the shafts might work. But it seems odd that this GM spec set up would be different length than the 465 combo.



Anyone got the 465 combo laying around they can measure?
Thanks!

Come on now, don't be shy. No one has one of these sitting on the floor?

LOL.

Seriously, need to find this out before I decide what to do with this thing.

Anyone? Just looking for a tape measure length on the units.

SM465 - 12"

adapter for NP205 - 7"

sorry, no 208

and this on the sm465

[mongocanfly]

and this on the trans and adapter...
.The SM465 is 12” long with an adapter housing of 7.250”. The transmission and transfer case adapter length is approximately19-1/4”. The overall length of the adapter kit is approximately 1” longer than the stock; therefore, driveline modifications may benecessary. The overall assembled length including the bellhousing is 26.250"

I crawled under the truck and measured. I got ~21" maybe a hair less for the trans and adaptor. Its about an 85 465/208 round pattern, which should make it a 32 spline. Its in a 72 truck so I can't be exact on the year...

A straight line from right edge of the bell housing face to right side end of adapter is 27 1/8" on my '84 k10. (SM465 to np208 with long foot adapter). I figure if I measured square from the bell housing it would be somewhere less than that...maybe 26 3/4?
