For helping keep this great

Again, thanks! | | | | Joined: Feb 2001 Posts: 1,094 'Bolter | | 'Bolter Joined: Feb 2001 Posts: 1,094 | I know that the drive shaft needs to be shortened 3 inches. I don't want to cut my original drive shaft. My truck is a 59 1/2 ton all original drive train. I procured another drive shaft and now find that the universal joints are not the same size. The caps are different sizes as well as the width across the joint. I seem to remember 40 yrs. ago you could buy a conversion u joint that would have different size caps, but I don't remember if the width across the caps were different. Any ideas from those who have done this already? How did you do this.
Thanks

Seems it is a common u joint that gets used.

One axis is the width and diameter of a 80's model gm product and the other axis is the size of the older gm products. They said it is a common u joint that is available anywhere if I ever needed a replacement.
