4l60 Drive Shift Lenth
I finally got a solution to my Drive Shaft situation. I wanted to use a good one piece but was concerned about clearance of the center crossmember where the carrier bearing goes.
Okay I have a 350/4l60 combo setting in the slots closest to the firewall.. My measurement from back of Trans (flange) to center of the flange for the U-joints was 67 inches. I went to a Bone yard and pulled out a shaft from a 1996 Suburban. Which is a HD Aluminum with plenty of Length for my application. The Drive Shaft Shop chopped 6 1/2 inches off and rebalanced plus installed a U-joint to fit the 1972 rear axle yoke on my truck... Great Fit, I didn't get any Pics of the shaft in my truck yet but if weather permit I will later today but here's some of the Shaft before and after Pics.. Oh yeah I had to remove the mount that holds the carrier bearing so the shaft would set in the center of the opening of the crossmember.... Hope this helps someone else looking to do a one piece swap.....

Re: 4l60 Drive Shift Lenth
That looks to me to be one of the driveshafts with the composite tube and aluminum ends. Did they shorten the composite tube?

Re: 4l60 Drive Shift Lenth
Yes it is Capt... They cut off both ends.

Re: 4l60 Drive Shift Lenth
I'd like to know how they did that. I was under the impression that those driveshafts could not be shortened.

Re: 4l60 Drive Shift Lenth
I needed about 6 1/2 cut-off, I believe the Sales man mentioned they cut each end splitting the difference...

Re: 4l60 Drive Shift Lenth
That would make the most sense but the aluminum ends look to me to be the same length as they were originally. I would think shortening them 3-1/4" each would be noticeable.
