This week I've been chipping away at some of the final welding on the rad shroud, as well as starting to tack weld together a radiator bracket structure to test fit and hopefully tack weld onto the existing gutted core support still on the car.

Test fitting the silicone high-temp seal in the channel...

Looks to have decent compression on the seal against the radiator... only mocked up the top and bottom seals so far...

Got some "4-row HD radiator bushings" from Original Parts Group, P/N ULR004.. they're the biggest ones I could find dimensions for on Summit so thought I'd give it a shot. They're close but still not big enough for my ~3.5"-thick radiator with shroud installed...

A little trim and they'll work with the mounting design I have in my head...

1" x 1" x 1/8" L channel on the bottom to tie the two vertical 1" x 1.5" x 1/16" rectangular tube side supports...

This is a trimmed 1/4"-thick L bar that will act as a base to mount the "bushing brackets" to.. I wanted to have some form of modularity when it came to supporting the rubber saddle bushings in case I wanted to adjust the front/back location of the radiator relative to the engine in the future...

Some 1/16" plate on the outsides of where the radiator will be just to add some rigidity and reduce flex of the bottom L channel...
