'65 c10 radiator core support bolts and radiator rubber pieces

['65 chevy lover]

I'm trying to find the core support bolts/rubber pieces and, the rubber pieces that the radiator sits in but, having hard time finding the correct ones. I had ordered what I thought was the correct pieces a year or so back and just now trying to get it Installed only to discover I have the wrong ones. Part of it looks right...the carriage bolts, the square pieces that the bolt goes thru to keep it from turning looks right but, rubber pieces don't look right. The size of the hole where it mounts is one inch in diameter but, the bolt is only 7/16. The rubber bushings need to have a shoulder on them To go into the frame otherwise, there will be way too much slop and wouldn't center the rad support. Unfortunately I can't download any pictures to show what I have. I also need 4 of the rubber pieces that cradle the radiator. They have to be about 2 -7/8" inside. Please excuse the poor writing skills I have. Hopefully Someone will be able to make sense of what I've written and be able to help me. Thanks in advance.
