Couple things to bring this thread back up to date.
During the christmas hollidays I swapped out the 4.0L for a bone stock engine that runs like a top.
I've also rebuilt the trans with new bearings and new syncros.
I've also replaced the fuel tank with a New tank. I didn't want to piss around with another used tank. I've replaced the tank once before and it developed a leak also. No more fuel leaks and I can fill the tank to the top once more.
Over the winter the latch on the spare tire carrier took a beating and the rust got the better of it. I ended up splitting the handle.

So I fabricated a new one along with a lock tube for the hatch struts. (Don't worry Mattie I'm still going to make you one).
This past weekend I gave the Bronco a bit more love. The cooling system got a revamp. The rad was leaking at the tanks and the thermostat I had installed was a 198°. It's getting warmer outside and it was having a hard time keeping below 200° on the Gauge. Again being sick of using used parts I splerged once again and got a new rad. Installed that and put a 192° t-stat in.
Everything is tickety boo right now.
Once the SCCA Super villan is together and on the road BIV will be going into the shop for a few and hopefully the last upgrades for a while.
