stevasaurus 22,878 #3 Posted January 7, 2014 (edited) In Gerry's link above, if you just look at the drawing, you count 4 pinions...but if you go down one page the number of pinions you need is 8. The 5091 transmission in the 1976 B-100 has 8 pinions. It looks like your GT has either 4 or 10 pinions. 4 pinion is WH 5086...10 pinion is WH 5073. The 5091 has 1 1/8" dia axles...the 5086 has 1" dia axles...I am not sure about the 5073 axle dia. Edit to say that the GT has the 5086 trans...4 pinion. I figured it out.
