FINALLY back on the road!

All in all I'm happy with the project. I LOVE the new look. Now that I'm though it, there are definitely some things I would do better/different.

1. Trimming the YJ fenders to fit CJ Tube fenders
There is no template for this. I was flying blind. I did a lot of test fitting, but messed up a couple of cuts.

2. I used the YJ radiator, should have used a CJ radiator.
I used a YJ radiator because I had a new one. I had to fab some custom brackets to get it on the CJ grill. Not bad, but problematic if/when I need to change the radiator. I also feel I could get the radiator as far back as it would have been with a CJ radiator. (See #3)

3. Fan/radiator clearance and shroud
There is about 1 and 3/8ths inch clearance between the fan clutch and the radiator.
That should be enough and I have Brown dog motor mounts to hopefully keep that clearance when wheeling. I also couldn't get the YJ shroud to fit. so I'm not running a shroud. I have to get a CJ shroud, plus I'm planning a motor mount lift so things should line up better.

3. Transmission cooler
I didn't lower the radiator so there was a clearance issue between the fan blades and the transmission cooler ports on the radiator. Instead of messing with it, I just connected the transmission lines directly to the B&M cooler. I know they say it's important to run the radiator cooler in the cold weather, but I hardly drive it in the winter. I'm just hoping that it cools well enough in the summer out on the trail.

4. Alignment of grill/hood/fenders
Not bad. The only issue I had was on the passenger side. When everything was loose, it was fine, but as soon as I started to snug things down, the front of the passenger fender would want to point down and the grill would end up crooked. The only way I was able to get it to reasonably line up was to jack up the front part of the fender which deformed the tub. I compensated by putting a piece of a spring shim between the tub and the fender. Once it's painted and with the rock slide over it, it's not bad.

5. Turn signals/markers
The YJ lights used a funky 4 wire set up. I don't get it, but according to the meter, 2 of the wires were both ground and 12 volts? I think it's how they got a 2 wire light to flash and alternate with the front lights. Anyway, I have the front markers/turn signals working. I don't really need them, but I have 2 front facing leds that are constant. YJ's and CJ's both had a side market/turn signal, so I have to figure something out there.

6. Loose ends
There is a tube that connected between the charcoal canister and the the air cleaner box. There was a bung right on the TJ intake tube, but I cut it off  :swear_mad: . I just have to make that connection.

Awesome project Rey!  For your fan clearance issue - a Flex-A-Lite electric fan would work great and free up some power.  I ran one in my YJ for over a decade and it worked great.  It has a built in shroud.
