CJ Grill on a YJ #techtip
« on: November 06, 2016, 04:54:07 PM »
I decided to change up Gorillacon and put on a CJ Grill. The plan is to replace the grill and hood and add tube fenders.  I will keep the yj fenders and trim them to fit the CJ tube fenders.

Our Race Jeeps where Commando's with CJ noses on them.

Should be pretty strait forward.  You may want to mount the "fender components" onto your grill support rods.  Wont take much more than welding some brackets to the rods and relocating everything..  This would also make future nose removal much easier for a V8 swap!!

Whats you plan for Lights and radiator?  CJ components and splice it together?

I'm not sure,  a new CJ radiator will be a cleaner install I think. The YJ radiator will fit (I read you just need to make some brackets). I'll use CJ lights, the headlight connector is the same, I'll have to check the turn signals.

Dont you have to shorten the height of the grill ?  I thought you did or it would slope upward in front. Its usually cut below the turn signals.  FjR68

Can you relocate the grill to frame mount?

The CJ grill has one mount in the middle and relies on the fenders to keep it level. I think the biggest thing is th Body isnt as tall as a CJ.   FjR68

I've got a body lift, so hopefully that minimizes the trimming.

I have a original radiator, looks like I might be keeping my scrambler tub and frame so I'll probably keep my body parts, otherwise I have everything for a CJ nose

Working on this slowly. A lot of checking and cutting, rinse and repeat. Trying to use as many YJ parts as I can.

The grill support rods are longer on the YJ, so I had to cut about an inch of new threads...

I've been slowly working on this, but here is an update.

When doing these CJ nose conversions, you should by rights swap in CJ fenders. There is trimming to be done and remounting of the stuff in the engine bay, but it looks way better than making the YJ fenders work. However, I decided to do tube fenders, so I bought Smittybilt CJ Tube Fenders (Smittybilt 76867 XRC Tube Fender with 3" Flare for Jeep CJ7)




Here is a shot before the dismantling. You can see the rocker guard will have to be removed. I did a half assed job when I got the YJ of fixing some rot on the rockers and when I took off the slider, I realized it got a lot worse. That will have to be fixed before the rockers can go back on.



This will turn into wall art, probably ceiling art because there is no wall space in the garage lol.



I started slow and just put the hood on to size things up.



You can see the difference in the profiles.



I had a connector in the YJ grill for flat towing, this is here for reference so I have the wiring.



I removed the YJ grill. Just a matter of the bolts on the side of the grill to the fenders, the light wiring, and unbolting the radiator. I test fit the grill to see what had to be trimmed.




The grill is just floating around. I had to get a least 1 of the datums or adjustments nailed down to start building off of, so it was time to trim the stock YJ fenders to work with the CJ tube fenders. They give you a template, but it was only marginally useful because of the mismatch. The top part, you are mainly trimming for clearance so the tube fender fits on and you maintain the bracket underneath that adds some rigidity to the top and inner fender and the hood latch bolts through there as well. I'll keep the bracket for the rigidity, but it won't help with the hood latch position because of the mismatch. you can see it in the pic.




I had never taken a YJ fender off before, so I cut away little by little learning the anatomy. Sort of like when we dissected a pig in High School. lol I tried a sawzall, but it bounced around too much, and I didn't like that the blade could easily cut something that shouldn't be cut. I used my angle grinder and cut off tool. More control, but the downside is all the dust.



I was trying to find the right position of the grill so I had a reference for cutting, so I tried to bolt on the support rods. The "CJ nose is 1.5" shorter than a YJ thing" came to light again. Instead of trying to source CJ support rods, I deided to brake out the trusty HF tap and die set and cut an extra inch of threads on both rods.




Another test fit, closing the hood, using the hood to estimate where the grill will end up.




I have a body lift, so I didn't have to do any major trimming to the entire bottom of the grill, just had to create some space for the power steering pump lines.




Here is a shot of the almost completely trimmed fender. There isn't much left. You cut off both ends (where the mounting bolt go to the grill and tub), so it's all willy nilly at this point. On the CJ, there aren't 2 sets of holes on the grill, so the the final step of bolting the top of the YJ fender to the tube fender will be what locks it in. Becasue everything squeezes in, there will be some work to get the coolant overflow bottle and the washer res to fit where they were.





What a PITA getting those tube fenders on! Definitely a 2 man job. Of course I couldn't wait for Geoff to get home to lend a hand. I should have video'd it. I was using straps, trying to hold up and position the tube fender while trying to get the bolts started without cross threading. I was literally pelvic thrusting the the thing. I actually stopped and had a good laugh about it once I go ttht first bolt started. LOL

The bad news is that this is a test fit to get the grill position, so they may have to come off again.





Loosely bolted in. There will have to be some panel alignment when tightening everything down.





The bottom mount of the grill will help center it better.




Since the front of the CJ hood narrows down, there is a lot of real estate on top of the tube fender for me to leave tools and drive away. lol.





You can see the inner fender just hanging there. I can see some sheet metal work will be needed to fill in some gaps.

That looks great. 

One thing we used to do with the race Jeeps it try to mount as much stuff as you can off the support rods instead of the fenders.  That way the fenders come off easy to work on the engine and the Jeep can be driven around with no fenders while working on it.
