Hello bolters,

The two holes for the core support mounts on my 49 Chevy panel, are either broke out of wallowed out, and I need to weld them up and redrill them. Anyone know the exact measurements on the holes? The one pictured is on the passenger side.

The one on the drivers side isn't nearly as bad. I have never seen any done like this.

My '51 chassis is sitting in the yard. I could measure them for you. Mine are cracked as well, but the bolt holes are still there.
But the FAM has dimensions of the holes. 8" between holes, which are 7/16" x 11/16" slots (long dimension front to back). From your pic, it looks like the front of your slot is still there, so you could go by that for the front-to-back location. Section 2, Sheet 2.00 if you want to check yourself.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.

Kevin,

Thanks. I didn't think about looking in the FAM.

I will check that out.

Set the radiator support on the crossmember. It might help you find exactly where the holes belong.

Thanks Carl,

I found the measurements in the factory assembly manual. Just want to make sure I drill them out where they are elongated for adjustment.
