u joint

On my 67 c10 i'm pretty sure the 12 bolt differential is original to the truck. The u-joints should be 1310s, I think. after installing them I realized I have about a 16 of an inch slop side to side in the pinion yoke, between the two tabs. Measuring between the two tabs I get 3.279. The 1310 measures 3.219 so that gives me the 16 of an inch. I have looked at Spicers u joint catalog and can not locate a u joint that measures 3.279. Is there a u joint that measures 3.219 and 3.279 the other? I know they make conversion u joints but those convert from one cap diameter to another. Is the 16 of an inch going to be an issue? I would think so but don't know for sure. Anyone run across this can shed some light on it for me.
