Used a license plate to make that. Sprayed the same color as the interior. Might make some additional panels for the other sections when the time comes.
Ordered an ebay aluminum radiator and some hoses as well. Going with T Bolt Clamps on them. I don't expect a whole lot, but the next step up was a mishimoto, and I'm scorned from the mustang days. Somewhere there was a review that rated and tested numerous radiators, and for the mustang, it actually cooled worse than stock.
I'll give it a shot and put some mesh in front of it to avoid too much damage.
More pics and stuff to come as I get this old girl prepped.
