Hi Phil

Thanks for the detailed info.

According to my C15 parts manual I seem to have two differetn size U joint....... 4 of the same for the front and rear driveshafts and two of different size for the short driveshaft that fits between the tranny and T-case.

Knowing that my truck was owned by a service station and that changes were made I am very cautious of measuring the parts I have found and beleive that they are original..... instead I will compare against other C15 parts truck first and look ofr original parts numbers stamped on the crosses. The Industrial Bearing solution shop I deal with claims they can help me.

More to follow later...... I may start a new string or ask Geoff to transfer some of this info on a new thread.
