Finalized the fan shroud mounting for the most part, 4 more rivnuts and it's good to go. The new assembly is 6.5" thick where as the OEM radiator/fans were 10" deep, if I get them mounted in the same spot I should have ample clearance.
Ordered up some 1/2" ID energy suspension bushings to use as radiator mount bushings. I need to weld some 1/2" rod to the bottom of the radiator and drill the required holes in the subframe (which I apparently have to straighten)
Expansion tank location, I will not be using the mock up tank in the picture as the sheet I used is too thin and I can only booger weld with 9 fingers it seems. I'll cut the rad cap fitting off the radiator, plug the hole and weld a 10AN bung on the back side right at the top as a fill point to be fed by the expansion tank. The steam vents are going to be plumbed straight to the tank with some 4AN hose.
