Need a new drive shaft what is everyone using

1350 shafts are used in a lot of 1 ton trucks. What are some pros and cons of cutting down one of these bad boys. The local salvage yard treats the shop I work at pretty well.

I measured to make sure the shaft I was using is the right length. Using the 1" rule it should be 47 7/8. The shaft I was going to use is 46 5/8!

The manual says 47.81 (47 13/16)
