Reproduction Body Tubs

[JZ1121]

Ok, yes, I have did a bit more digging. Apparently on thr CJ2A feed, people had the issue of missing body/frame numbers and it was common practice to use engine serial numbers, and the likelihood of the same serial number showing up for another jeep was very slim. So yeah, I guess I'm going that route.

And yes, back to the original topic. I say, go original as best as you can, and see how much can be repaired. If it is practically a pile of iron oxide, then consider the repros if you can't get another likewise original tub.

Also, Ron now stocks the JMP bodies for late ACM Willys and Ford bodies; now, they are just the rear half. You will have to buy that, and weld on the front floor, sump, and the two front side panels, onto your existing dash/firewall.
Of course, this is not drop in either and you will have to weld and drill lots of holes; I would say that if you are expecting anything to just drop on and bolt in, you probably should not be restoring old jeeps.
Here is the link to that.

Hi,

The statement above about JMP rear halves needing holes to be drilled is completely incorrect.

The panels are laser cut with ALL holes and assembled on trued and checked frames at the UK facility.

The only hole you MAY have to drill is the upper securing hole for the two hole spare wheel shoe but even that has a mark in place to do it if you have that need.

When mine arrived (early last year) it took me less than two hours to graft it on to my pre-prepared front end, just spot welding across the riser and floor seams, the side joint and then MIG welding in a few places and I had a whole tub.

Having used an early SGI tub to get to Normandy in 2019 when my ‘44 tub was caught in the JMP fire, I’d use JMP every time I need to!

Are all the holes drilled in the front floor? I said drill lots of holes, not drill ALL of the holes. Point I am trying to make is, that this COA is not a drop in kit and it takes a lot of work to make it work and fit. People who tout how great this is, don't consider that lots of guys just don't have the skills or patience to make this work. That is the point; not holes.
You are lucky to have a front floor, sump, and front side panels; none of the jeeps here have those intact, including the 44MB I will work on next. To get a complete tub, you will have to. buy that rear half, front floor, sump, and left and right side panels, and hope your transmission hump is good; otherwise you are screwed. And weld all that together, onto your existing cowl, and yes, drill holes. I see no pre drilled holes in the picture. Salt in the winter and humidity worse than Florida in the summer (from all the corn) .Two hours of welding is dreaming because no jeeps I know of just require the rear half of a tub. I still don't know why they don't just make a whole tub. Half of one is, half of a solution. And my cowl/firewall is mangled up too, so...that's a bad thing.

Hi,

I only had this rescued from SWMBO’s ACM1 tub:-



Using ONLY JMP panels I rebuilt the front floor and cowl sides, the only panel JMP don’t do is a floor with the hump, so the only difficult welding was the but seam around the hump to floor. The rest is spot welding and I have an hand held spot welder for that. ALL the holes are laser cut in the floor and hats before folding/forming.



As I live 45 mins from JMP HQ and have a previous tub restored by them, I asked if I bought all the components for a rear end, would they jig assemble it for me. (I like to think I may have planted the seed for the rear tub commercial venture). Once assembled, I collected it and completed my tub.

I’ve spent over 41yrs in the military and civilian defence world as an engineer but vehicles/metalwork are just a retirement hobby now. I’ve had to use a full repro tub as a temporary solution and I’d use a JMP set of panels, however they are assembled, any day of the week.

Here’s the completed tub, final assembly and painting by me in my home garage.



I know JMP restore around 20-25 jeeps a year in their workshops, either “customer vehicles” or for sale, all use their own panels , so I know they are well QA’d, as any issues are immediately fed back to the design & cutting team.

TBH, if you make a set of jigs/supports like I did, and have reasonable welding skills (I’m not an expert and am self taught), all you need is patience and a tape measure and plenty of clamps to produce pretty good results. Far less pain than 20-30 patches all over a rusted tub.

Looks very nice. And you are lucky to live near JMP. I could certainly weld it all together in my sleep, but no other guys I know could do that. So, why not just make the whole tub? they would sell better than parts. Also, someone will have to start making the transmission hump. Mine is gone (half rusted away) , and lots of others are too. As I see it, speaking for other jeep restorers; the JMP route is not viable for them. They need a tub that they can start with. Not half of one. All these automotive and technical skills are rapidly being lost; and I am tired of everyone here asking me for help,
(Actually I'm not; got to put a clutch in for a friend next week; he doesn't know a clutch from a brake shoe)

Hi,

If you read a previous post by “slopes-2”, he explains why JMP do not and have no plans to do full tubs.

It’s one page 1 here:-

I read it...not helpful. There are ways to make it work/fit. Just make the whole tub.
For example, my transmission hump and firewall is trashed; I need the whole thing. So JMP rear half does not help. And there are others who are in the same boat.

And then there are folks like me. If / when I decide to restore my Jeep all my body needs are the transmission hump and firewall.
