What is this?
My name is Tony and I have just become the owner of the second CJ5 I have ever owned. The problem is I don't know what I've purchased. The VIN is JOM83AB720838. I've used the VIN decoder but the engine description says N/A. The B in the VIN on the firewall is definately a B. That is also what is shown on the title. It has a AMC 304 , 4spd, power steering, power brakes, factory tach and clock, volt, oil pressure, and dashpad. Can anyone help me figure out what I have? Thanks!

Hi Tony, welcome to the site!
Far as I can tell, You have a 1980 CJ5 made with a 4 speed SR4 tranny mated to a Dana 300 Transfer Case . The GVW is 3750
I'm a bit confused on the engine code, are you sure It's a B and not an E?

WHO'S YOUR DADDY!
This is the second time TODAY, that I have found the "B" engine code on an 80 CJ. I wonder if there is any chance that there was a cross over for the low comp AMC 258 i6 / 4.2l 's that ended in 1979 used up in some 80 models??

I went ahead and merged these threads... 
I'm going to have to do some digging in my books and see if I can come up with a 'B' engine designation...

Re: What is this?
Tony, that is literally the second time today that I have found that B engine code on an 80 model CJ. I have no reference for that code in 1980. All I can figure is there may have been some hold over engines, but I really don't know. The V8 could well be a swap in engine. There are other #'s above the VIN code, one will be a color code, and others will be destination and options codes that I can't decode with my reference

Re: What is this?
Well, I did find one source that shows a 'B' code - for a 2.5L GM 151 4cyl in 1980, but another source shows 'B' only from 81 up. I'm pretty sure you have a CJ5 that originally came with a 2.5L.
I'm going to try and verify that now...
EDIT: Found another book with a 'B' in 1980. It also shows a 2.5L.

Re: What is this?
Is there a resource for decoding the other codes on the VIN plate?

The correct color for an AMC v8 is blue. I still have the original oil filler for my v8 and it's still kinda blue. Eastwood sells it... Eastwood High Temperature Ceramic Engine Paint - AMC Blue

Re: What is this?
Can you post what you want decoded? I have books on CJ's. I'm sure we can help.

I do for some years - I believe that 80 is one of them. I'll have to dig out my books.
