Got the radiator mounting complete. 1" angle bolted to the bottom of the core support with slit vacuum hose as a cushion. I decided to bolt rather than weld incase I ever do the 98+ facelift. Then I can just transfer the angle iron to the new core support. I forgot to get a picture of the finished bottom with the radiator mounted, but it's very similar to what I had before. Just now it's painted and the vacuum hose runs the full length.

For the top, I went with a couple straps of 1" flat stock bent to suit. Again, using slit vacuum hose as a cushion. Just enough to hold it forward against the core support.
With a little bit of trimming, I could still get the original factory upper fan shroud on there. That's probably something I'll do further on down the road to maintain the look I'm going for.
Once I was happy with the radiator mounting, I very carefully set it off to the side and worked the core support back onto the truck
Still need to run all the bolts in, feed all the wires through and secure the grounds, but it's starting to look like a truck again!
