[Roger Bolick]

This pair is built from all new Spicer parts and has the 1410 series U-joints, a competition upgrade. The Yokes near the diff rub on the original filler panel, so either the hole needs to be enlarged slightly or the corners of the yoke trimmed.

To the best of my knowledge all the current KMS and CSX cars have the larger filler panel hole and some of the originals may have been done this way or converted for competition.
