Default 75 rad support help!

Hi all!

Installing a new rad support in my car (when I got it it didnt have one) and was wondering what size hardware I need to mount it, as well as, does anyone have any pictures of how they mount in 75’s? Surprisingly hard to find any clear pictures of them in cars..

thanks!

The six bolts 3 either side are 3/8-16. Bout inch or 1-1/4. So are the hood hinge bolts and radiator brackets. The big ones in bottom are 1/2-13 or 7/16-14.

I am pretty sure that the bottom bolts are 7 /16 - 14. The company that I worked for, for 34 years in maintenance made the Corvette radiator supports. I remember keeping a couple of the lower weld nuts
because they were an uncommon size in our factory. Lou.
