I have question about drive shaft length. My drive shaft goes in to the TKO 600 about 6". I have to pull it back about 2"- 2 1/4" to connect it to the pumpkin leaving about 3 3/4"-4" in the trans. Is that enough, or is that not enough?

Sounds about right to me if you've got 3/4 of the slip yoke in the tail housing.

Actually, looking at his numbers he has about 60%-65% in the housing.

1"

Ideally, you should only pull it out about 1". If it has too much play you will have vibrations and wipe out the tailshaft bushing quickly.

I was told by the local company that made the driveshaft, that since it has the 6" long TKO input yoke, that pulling it out 2" was "OK".

I was not convinced with his statement. And 2" seems to like a lot. Just wondered if anybody else knew for sure.

I just talked to 2 other drivetrain specialists. They both told me 1 - 1 1/2" is best. Not any shorter. So I am returning the short driveshaft and hopefully getting the longer one about the time I finish the radiator!
