Radiator mount support

[freds]

Hi,
In the final stage putting together the my 1967 Chevy c10 pickup, and have run into a problem. the radiator mount support mount holes are way larger than the bolts, the mounting holes dementions is ( 1" 3/16 diameter) and the mounting bolts is ( 7/16 ) lots of play. I've received the mounting bolt kit for that year. further reviewing shows the 1969 kit has a rubber mount that goes directly into the hole and seat tightly in the hole ( no give while in the hole).
Has anybody experienced this problem and if so, how was it remedied ?.
