trans question ?

[my old truck]

i have a 94 blazer 4x4 with a 460-e trans i also have a 350 tubo trans out of an earler 4x4 pickup i would like to use the turbo 350 trans so i can do away with the computer,my question is is there a adapter sleve or mount for the end of the turbo trans because, it has a shorter in put shaft where the trans bolts to the transfer case,the splines are the same no# but the shaft is shorter and the trans is 21 3/4 in length where the old blazer trans is about 23* in length and the shaft sticks out 3" on the blazers 460-e and the old turbo only sticks out about 3/4". any help would be very much appreciated, thanks
