Grey paint color code is FEDERAL STANDARD 595B 26134. The 20 had 2 diff styles of hood latches, first you need to know what style yours had. I cant beleave you would go to all that trouble restoring and not put the orig. mag back on it
Thanks for the paint information. I wasn't aware there were two kinds of side panel catches. I do know it takes 4 and they hook into round holes on the solid panels below the louvered engine curtains. My SN is PL 4035 so I'll look them up in my parts manual.
I don't think the Eisemann mag my dad removed was the orig. mag. It is similar too, but not quite the same as the drawings in my parts manual.The WICO mag on the machine is really hot and the tractor often starts with just 1 or 2 pulls. So I think I would be wise to leave it alone.
If you have the holes in the lower engine side panels then its the late style and you can still buy them new from Cat Dealer part no. T537 they call it a fastener, that is a Cat ten number but the should be able to cross ref. and get new part no.the same latch that they used from the 30s til modern days up until they started making rubber fasteners. early were made from cast parts and put together and take apart the later ones were made of stamped metal and put together so you cant take apart but most people cant tel or dont know the diffrence
