I have a 1989 Camaro RS Convertible with a 5.0 and 700-R4.

I just put in the 82-92 Camaro Ron Davis Radiator Part #: 11-16CA8292T with the dual electric fans and Aluminum top mounting plate setup.

Problem is, when I pulled my old setup out, every stinking one of my top radiator mounting bolts is FUBAR, so much so that I cannot determine the correct thread pitch etc.

I was unable to find any 3rd gen radiator mounting hardware kits googling.

So here I am, to see IF anybody knows the bolt sizes and or if anybody has a source, part number etc for a hardware kit with these bolts and the nuts that slip over the radiator core support for the top radiator mount hold down bolts to screw into?

thanks in advance.

 

I'm not sure which bolts you are referring to. If they are a fine thread then they should be a Metric 6.0 x 1.0 That size is all over the body. Otherwise a standard sheet metal bolt will work, #10 or #12 I think.

 

I'm inquiring about The bolts that hold down this top piece that the upper radiator rubber mounts sit in. The heads of the bolts are 1/2 or 13mm.
