    Posted: 13 Sep. 2021 at 10:48am
Hey guys new to the forum, there wasn't a new member intro thread that jumped out at me.  My name is Josh.  Currently living in Hunt County Texas about an hour east of Dallas.  Currently work as a Firefighter/Paramedic. Been into Jeeps since I was a kid, mostly owned XJs, my current 1995 Daily Driver XJ is my 4th.  

Last year I rebuilt a 76 CJ5.  Took it back to a mostly stock condition about the only things that didn't get rebuilt were the front axle and engine.  

Anywho on to my current project.  

This is an unknown year CJ2A.  Owner had it listed as a 1950 CJ3A, I posted on the Early CJ5 forums and those  more knowledgeable than me on the subject said that it looked like an earlier 2A with a 3A windshield. Original Seral Numbers were missing from the frame and the firewall data plate but the tub still had it's number "151274"  If I'm reading the serial number document right this should make the frame around 161274ish?

Anyway today I'll be going around and starting a parts list and getting the body removal started.  Current plans are basically like my CJ5 but add the front axle and engine to the rebuild list.  It does start and run, but for sure has a blown headgasket, we started it to get it up on the trailer and again when I got home to get it in it's semi-permanent spot in the drive way.  Once I get it to the point it's ready to go back together I'll move the project into my garage and let the XJ live outside for a little while.

The acquisition of the 2A has spurred me to finish the M416. Or at least finishish. I didn't spend a lot of time on the frame. Basically knocking the lose stuff off then shooting with primer and CARC Green.
Ill finish the fenders tomorrow and have it assembled and out of the way leaving me with the 2A project.

Here is the current data base.  ==



The ACM tub number is not an exact science because of the way Willys Overland pulled from and stored inventory, but the data base suggests it's an early 1948.  If we assume your engine is original, (this is rarely true) then it is a 1948 CJ2A.

I thought about that.  The previous owner rebuilt the brakes, and steering so for the short jaunt down the road and back it steered and stopped well.

It does, it at least is more confirmation it's a 47.

That link gives me a 404 error.  Nevermind got it to work

Some guys over on the Early CJ5 forums were saying they thought it was maybe a 47 or 46 since it still has a full float rear axle?  Which they said was a MB part that carried over into the early CJ2s.

The picture is not clear enough for me to have seen the rear axle.  That said, the numbers you have listed do not coincide with a full float axle.  Based on the current information you have given, you still have a 1948. The 3A windshield and the full float axle just tells me it's also a hodge-podge.

Can you show us more pictures of the frame...and the engine compartment?


Edit...FYI:  I think I fixed the link above.

I'm rolling out tomorrow with the CJ5 to go to an event in Arkansas but I can try to snap some in the morning.  Is there anything specific I need to capture in there or just a general overview of the engine bay?

  That just goes to show ya - those guys may know their early CJ5’s, but they don’t know squat about CJ2’s and CJ2-A’s. Most of them probably don’t even know there is a difference.
A ‘46 might have a full-floating axle, but a ‘47 certainly would not. And the full-float axle is not a carry-over from the MB. MB’s had 4.88:1 gear ratios. CJ2’s and CJ2-A’s had 5.38:1s.

They mentioned the gear ratio change.  Maybe "carry over" wasn't the right term but they said during early CJ2 production they were still using left over parts from war production stocks.  

Either way the forum there is a great resource just like this one.

I’d be checking the axle ratios to be sure they are the same front and back, just in case someone swapped a military axle for the faster top speed or as a junkyard replacement.
Is the bellcrank attached to the front axle or the frame?
Salad or not it looks like a great start.

Wow, that's a statement. There are a lot of good folks that know a ton over on ECj5. Lots of them have flatties and know them as well and are willing to share, but I guess they "don't know squat".   So your saying that Willys didn't use the full floating MB axle on the early Cj2A's because the axle ratio was diff?  Come on, Willys always retrofitted what they had left over on the newer models till they where gone. Heck, some early Willys rolled off the line with two solid rims on one side and slotted on the other, along with other oddities.

  Embarrassed  Alright, I’ll retract that. I’m sure there are some very knowledgeable folks over there. I don’t go there anymore because I don’t have a CJ5.

Got the hood, fenders, grille and windshield frame pulled and set to the side.  Today also involved mostly finishing up a M416 trailer.   Hope to have the tub off this week if I can wrangle some friends over to help lift it off.

Welcome to the page, Downs!

Your passenger-side front fender is from an MB or GPW.  Driver's seat frame looks like a 2A but the passenger seat frame is too hard to see.  It might be from a 3A, but maybe not.  How long are the rear wheelwells?  From the back panel to the front of the wheelwell, a 2A is 35-5/16", a 3A is 32".  Got any more pics?

That's one of those tools I need to add to the garage, I usually just borrow one ha.

Here's a few I took before leaving town last week.  I'll have to measure the tub when I get back from work tomorrow morning.
