i dont think those exist but could be wrong might have to cobble something out of a 4x4 or van(a100) combo?
904's are shorter than 727's. The only shorter ones I know of are 4X4 units, but they are made for a transfer case to bolt on.
I think the A-100 vans and pickups used a shorter tailshaft transmission, but I have been known to wrong a time or two.
i got a 70's ram (adventurer) with the little jump seats in the extracab. It was a 360 model, short tail with a bolt on yoke, two piece shaft and carrier bearing. A short shaft with a slip yoke would be cool. keep an eye out for truck trans- good source of small block 727s. although a truck 904 from 70s frequently had a deep first planetary- 2:76 instead of 2.46 and that got my heavy boat out of the hole pretty decent.
Motorhomes use a shorter tailshaft than the pass car trans but they also have a parking brake drum on the back
A-100s (leave 'em alone!) Divorced transfer case 4X4 trucks (early 70s) A body was shorter than other cars. EDIT, the 4 speed shifter location was different. Auto trans was the same. The first 2 have a bolt on flange, so driveshaft will have to have the slip joint. A regular car (66-up) trans will have the slip yoke on the back of the trans.
I have a good SB MOPAR engine 727 core but I don't know what length it's tailshaft would need to be to be considered a "short" one. Make me a reasonable offer and you eat the freight and it's your's. pdq67
904's and 727's unless they were in a truck chassis as mentioed above all have the same length meaning 904s are one length 727s are another
The short tail 727s came out of pickups and full size vans in the mid to late 70s and divorce transfer case 4x4s (big and small block versions were made). Never seen one with out the bolt on u joint flange. The drive shafts have the spline section about 8" behind the front u joint, or were the 2 piece ones with the center carrier bearing. I believe they are about 6" shorter then a standard 727. Being a truck trans often used in heavy duty applications, they tended to have a bit more heavy duty parts inside. Finding drive shafts with good splines and couplers is getting to be a challenge. Gene
IIRC, There are actually 3 tailshaft lengths. The normal 18" or so in 2 versions, beefy truck with side circlip access and normal auto with bottom circlip access, a 14" or so that makes it the same size as a 904 end to end, found in vans ( i needed a short shaft 727 for a replacement a long time ago and thats what they were looking for on the salvage squawk box) and the super short 8 inch that didnt have a slip yoke, used in motorhome chassis and other special stuff.
