New Driveline or Donor Driveline Shortened?

[BANKO]

Hey Guys, I am doing a Viper T56 swap into my 65 Chevelle. The car has a 10 bolt and 1310 u-joints. I need to swap the trans yoke to match the 30 spline Viper output shaft and I'm considering moving up to 1350 u-joints requiring a pinion yoke swap. Not sure if finding a donor driveline out of a 1/2 ton chevy truck (with 1350 u-joints) shortened for application is a good idea or if I should move up to custom Chromoly drive shaft. I am concerned about critical driveline speeds as I will be keeping a 3" shaft for tunnel clearance.

I'd get a price from IEDLS then decide.

Their service and turn around time was great when I did my conversion and I ended up with a stronger driveline. :thumbsup:

Hey guys, I went with Steve at South Bay Driveline (http://www.sb-driveline.us/)

He did a great job and had a single day turn around, actually he did it in 4 hours! He was a huge help and made my T56 swap happen smoothly.

I've used South Bay Driveline and San Leandro Driveline locally in SF Bay Area. Both shops have similar pricing and fast turnaround.

A 1350 series Ujoint is miles stronger than a 1310 series.
