I seem to have misplaced my hardware that secures the radiator to the frame. My truck is a 1977 FJ40 with a NOV 76 build date. I have been trying to get it to a point where it won't deteriorate any further. I'm not trying to do a restoration, that will come later. I removed the front clip and degreased everything I wanted to paint with POR-15 frame wise. One of the items I removed was the radiator. I cleaned it up, re-painted it and I am now at the point of re-installing it. Unfortunately I cannot find the nuts, washers and split washers that secure it to the mounts on the frame. Can I just go to Tractor Supply and purchase hardware (metric machine thread) to secure it with, until I find the original hardware? If so what size nut do I need? I really would like to start putting everything back together again, I have had the truck in pieces now for 8 months. Also does anyone sell either OEM or reproduction shims (material pads that go between the bottom of the radiator housing and the frame mounts), I have looked and even gave the part number to my local Toyota parts department and was told it was a discontinued item. Thanks for any help or advice in advance.
