hi all
first i better introduce myself my name is chris , ive just discovered the wonderful world of G5O3 and i must say what a fascinating corner of the internet submerse yourself.
Ok ill explain my situation I own a willys MB in bits i have the frame,tub no engine block,i do have the majority of the parts all original.
I`m certian the chassis is ww2 of course the tag is missing but the holes are there,the tub weather it rolled out of the factory with it we`ll never know.
The tub is a early one typically the glove box door is missing however i do have a number which is 104106 from what i can gather is early 43 ?
I want to restore this jeep as original as i can, i would like to Put a tag on the chassis, reading around it seems buying some old plates off a scraped jeep might be the best option
so here are my questions
Can a rough dod be worked out from this tub number ?
what would be and acceptable range in numbers for frame serial dod to match this tub ?
What would be an acceptable range in numbers for the engine block to match ?
I know we`ve got the the cream here when it comes to people with knowlege on the willys i would be most greatful if someone could help
many many thanks
