Weird problem.........
 

I can not get hubcaps on my truck. I've tried 2 sets and neither will fit. I've got 71/72 hubs (I think) from napa, could they be wrong?

Youy have any pics?
Are these car hubcaps? They won't fit on truck wheels, they'll be too small.

Oops, I said hubcaps, i ment dust caps, that cover the castle nut and bearings on the spindle. I can't get them hammered on for anything. One cheap set from napa and then ordered one set from ECE. I'm runnin straight ralley's with no trim rings or anything.

ahhh, that does make more sence.
Is there a chance you have later hubs? How far off is it in size? I'll assume the caps ar just a hair too big... you might get away with putting the caps in the freezer for a while...I wouldn't heat up the hub though. (seen that recomended here before)
