My 1969 with air is missing the two lower bolts that attach the condensor to the radiator support. If I lift the condensor away there is a rubber grommet with what looks like a nut inside the rad support. I tried to guesstimate the bolt size with no luck! the assembly manual (pg 265) shows a screw going into a grommet (p.washer)? Is anyone familiar? the core support is not accessable from the back. Any help appreciated to unravel the mystery of what's in there and where can I get a new replacement to stop the condensor from flapping around. THANKS

is it a small machine screw, I would thing that the rubber grommet has a threaded steel or brass insert in it. It could also be be sheetmetal threads instead of standard SAE threads.
