length of the thm200

the overall length of a thm200 in firebird would be 28 11/16" right ? tail mount is farther forward or back than a th350 ?
output is same size spline right ?

just checking,
thanks,

Axle/Gears: 12B-3.73/9"-3.89
Same length as 6" tailshaft TH350, mount is farther back on the TH200.

Can't say for sure about the splines, I believe they are the same, though.
