Re: Replacing a Rockwell T221 with an NP205
1969K10
I have ordered a new driveshaft from Tom Wood's Custom Drive Shafts out of Ogden, Utah. They had no problem with the length. Mine needs to be 58 7/8" with a 4 degree slope. It has Spicer 1350 u-joints at each end and a 3" slip joint. Tom's only advice was to increase the diameter from the original 3" to 3 1/2" which I did. He has an excellent web site that provides you with a "Complete Measuring Guide". He is well known and respected among 4WD gear heads that do a lot of off roading with highly modified (lifted) vehicles.
