[RPRICE]

excelguru, i had the same problem with the ford wheels. my problem was not incorrect pin diameter, but out of round pins. the pins are very soft anyway and my pins were "bulged" out of round when the allen head drive was tightened. took the pins off and tightened them on a 1/4 inch carrage head bolt and nut. chucked the bolt up in a drill and spun while holding fine sandpaper against the pin. could see right away the high spots. when they were gone, pins fit fine into the wheel. have had to redo a few pins as the adapters are removed for rotor work, etc. hope this helps. but btw, there have been different pin diameters used on various wheels combinations used by SPF. if your set up was all new from trigo, this should not be the issue.
