howdy there,

people should realize/remember that there are three lengths of the th350 in 2wd form

700r4 is the same as a th350 with 9" tail

found in some vans, some full size cars and wagons, and all full size trucks

ppl dont seem to understand this

there is more than one th350

plus there is also a lockup converter variant of the th350, it is call teh TH350-C

i have one in the basement original to a '81 C-10 pickup 350 olds diesel i parted and junked. 10 bolt bellhousing to fit all GM 90 patterns


you need to measure the tailshaft housing length to know what trans model will fit in place of it

but since i see it is a camaro i know it is the 6" tail length and a 700r4 is 3" longer than these, so you need a 2004r in which is 4 speed auto and will fit right in place of the th350 other than crossmember location

however, if you have an old arc welder you couls simply cut off 3" of the driveshaft and use a 700r4

i am doing the same thing because i am swapping from 9" tail th350 in my 78 c-10 pickup over to a 1987 3L80HD trans(th400 body with 27 spline output shaft and it is 3" longer than a 9" th350 trans)

very easy to cut and re-weld a driveshaft

did the same thing for my 2wd s-10 pickup not too long ago, i replaced the original two piece shaft with an 89 full size van single piece shaft, had to cut 1.5" from it to fit the s-10


also it is hassle, not hastle


good luck
