Hello
I have a 67 chevelle malibu original with 283 an PG but no i have a 454 and th-400 and i have to shorten my driveshaft. Anybody here who have done the same? How much did you shorten it?

Best Regards

Call up the local driveline shop, ask them how they want you to measure it so they can cut down the current driveline, or make you a new one. Get it balanced also.

I'm not condoning this but back in high school a buddy of mine made a long bed Chevy pick up into a short bed, he just cut it and welded it back together, it didn't even vibrate..

Do you expect us to belive that................... :)

Some things you may not know, the TH400 is a 32 spline output, the PG is a 27 so you need a new yoke on the shaft.

I think the cross member is in a different location and the length thing is best measured by you so you are responsible when it's wrong, or right:yes:

Let the shop who will do the work tell you how they want it measured.

Thanks for the answers. :)
Yes i know i need a 32 spline yoke, but i dont know the right way to measure it but the driveline guys should know it..:yes:

I just got one made from the drive shaft shop in north carolina. I told them what I had, and they just told me how to measure, and made it up. Plug and play. Was about $375, a lot cheaper than most places, and that is because I had it made with 1350 heavy duty yoke and Ujoint since I replaced the one on my pinion to a 1350. They said would be good to 800HP, and they balance to 10K rpm. Anyway, just a suggestion.

They told me to measure from the back of the tranny, not the back of the output shaft, and to the center line of the yoke.
