U joint Question

Ran into that problem too 67dart273, Tried getting the cross from the neapco 2-3100 from napa which was a spicer 567 somthing and was completely different. I dont think changing the caps on the 7260 would work because on the ford rearend wich im using from a 76 granada i have about 1/8 of play on both sides of the caps where it fits between the two tabs that keep it centered on the ford yoke. i tried using halfass shims and workd for a couple of weeks but ended up destroying the ujoint.
Yea i have the 2.79 gears. Superhighway gears especially with the 5speed im using buts its good to go tho. Using the stock driveshaft, however its behind a 5speed and its alittle close but adiquet. Gona upgrade the driveshaft tho later on.
