OK so here is the plan I am building a stand-alone radiator support for My YJ. I am doing a CJ front clip swap and haven’t really come up with a good way to attach the radiator to the grill. I am using an M38a1 grill since my cj-7 grill I picked up is a rust bucket. The M38 doesn’t have much of a support for a rad and what is left of the tiny one it originally had was torched off, besides I like the idea of them being separate from each other. I am in no way an expert on building something like this, but I can weld and fab. So I come here to show what I have came up with and what I plan to do. I hope to hear good feedback.
I am using 1”x1” 1/8” angle iron that I had lying around from another project, that should be sufficient. the main support will be rectangle utilizing the existing rad mounting holes. then I will build supports from the frame to the rectangle framing then bolting it together where they meet.
I have included a pic of what I propose to do and the supports I plan to have. This is what I plan to make with some minor tweaking

Obviously the red is what I plan to build with bracing going down to the frame. (Mad paint skills) I will tie it into the top of the grill for a support and will also tie the grill into the YJ support rods with some custom brackets. I will take some pics of the grill and post them up I just wanted to get the ball rolling and see what kind of feedback I get. Like do I need some kind of isolators to keep vibration down? Will I crack my radiator mounting it this way?

What it looks like with the CJ grill on and a link to my build thread:http://www.jeepforum.com/forum/f12/s...build-1467426/

Then bolted it up to the rad. Tack welded the nuts to the back side.

Ok on a serious note!! does anybody have any suggestions on whether I would just hard mount this to the frame or should I add some kind is dampner. Like a rubber bushing. I have an idea to use my old track bars as supports down to the frame. Similar to how you would use a YJ leaf spring bushing for a motor mount. Any help??

I would imagine you would want some type of bushing or something in there. Even if its like a body lift style bushing(or a hockey puck) at either side of the frame rail like my old nova has for its rad support

I dont think the body mount gave it that much dampening.I know tons of mud runners and trail rigs that are hard bolted to the chassis and they dont have any problems

My thoughts exactly! I was throwing it out there, I suppose it still wouldnt hurt to dampen it anyways. I got to come up something to use my old track bars for and this just may be the ticket. Should get some fab time in this weekend Im super busy tonight and Friday with my Sons Cub Scout fundraiser, but feel free to give more input fella's. Im getting anssy to get this thing running again its been out of comission since before Christmas

Well I started fabin the mounts for the support to the frame. I'm not too sure I'm happy with how its coming out. I kind of rushed the design and not to sure I like it. I think I will work some more on it and come with up with something. I'm always open to suggestions.

I worked on it some more last night. This is what I came up with. I used some tube I had laying around and some 1/8". I sure wish I had a plasma table it would have came out nicer.

Made some more progress on it this morning. I home with my sick son. While he is taking a nap I plugged in the baby monitor and went to work. Rad mount is tacked in now just working on mounting the grill. It's a lot of work to make this work but worth it in my opinion. It probably would of been easier to find another CJ7 grill but I love the nostalgia of the m38. I have something from most every era on my jeep from M38a1,CJ,YJ,TJ,FJ,and ZJ I plan to source parts from a jk next. lol

Ok huge progress this morning!! I even had a little helper until I started welding.

I cut out all these brackets with my trusty 4.5" angle grinder and cutting wheel. I used a scrap sheet of 1/8" I have had laying around from other projects. I made these upper mount strut supports for the top of the radiator mount, and drilled some holes for a little affect.

Pulled it again to weld it all up. I had to make that notch in it for the headlight bucket to fit.

Then primed and painted it.


Then I got to making the grill body mount. The mounting point on the M38A1 grill is 2" inches farther back and about 1.5" inches up so I came up with this mount.

Im kind of frustrated cause my camera erased the side profile shot of it before I painted it but here is a shot of it with a fresh coat of paint.

Today was a pretty productive day just got to wait for all the paint to dry and install the oil pump prime the system and hopefully it will start. then I can install headlights and figure out turn signals
