    I have a frame that I bought with some other JEEP parts and i need some help IDing it.
    It is from a flat fender, has round front crossmemberwith bell crank on it. 123" long. The rear crossmember has been removes wand the X member.
    The springs are the U type. Cannot find any numbers on it. Had 134 motor mounts that were removed.
    The frame has been sandblasted and found only one crack in one rear spring mount.
    Any help guys

    From our own tech library:
    http://www.earlycj5.com/homebrew2/M38-Power Train, Body, Frame.pdf

    The stated frame length is real close to being right. 122 and 3/4' vs. 123"
    The round front crossmember makes it a Willys, but I don't remember if it was just the military frames or if the civilian ones also had it. Some one will correct that, I am sure.

    Also there should be numbers stamped in the frame in a couple of different places that can help.

    If it's an old military frame there may not be any numbers.

    Civvy had a round front crossmember as well. The numbers would be stamped on an ID tag on the left front frame horn. The tag was mounted either inside OR outside depending on year it seems (I have seen them both ways)

    Military would have had a machine gun mount plate on the crossmember over the wheels. I do not know if this would apply to a V35 however, as V35's had Civvy style Willys stampings and grill, I do not know if they had a civvy frame or not. (these are pretty dang rare, so I doubt you would have that anyway)

    CJ2A and 3A are almost identical (almost) and the CJ3B frame I have been told had some very distinct changes.

    I would try www.thecj2apage.com with some pictures, when it comes to flattie jeeps those guys are comparable to snipers... They can spot things and nail them at 1.5 miles and not even flinch.

    Not a WWII military. Their bell crank is on the front axle.

    My guess would be a 3a or later.. Do not see the mounting tabs for the tranny Xmember that a 2a had.. If the motor mounts are directly across from each other, not off set, it would be a 3a or later.

    To correct a few things with frames. Not all military jeeps had a machine gun mount. The cjv35 u and m38 do not have one. The cj3a and 3b share the same frame, along with some very late cj2a's. The way to tell an m38 frame from a cj3a frame is the that m38 frame will be boxed behind the bumper to the front crossmember and one have a place beside the front crossmember for the grill to bold on, it will have hinges instead. From looking at the pics it looks like you have a cj3a or cj3b frame.

    Now M38's were 24 volt and the battery was in the cowl, this one had a in engine compartment right front.
    So that rulls out a M38. So it is most likely a 3a or 3b,
    Were did thaay stamp the number on the frame, I looked but could not find any, now it was getting dark when I got home with it.
    Do you think this would be a good start for a build up of the CJ3A I have , the front of frame on it was cut up a lot.
    Can I get reproduction X member and rear cross member for it.

    m38's use two 12 volt battiers to get the 24 volt. One is in the cowl the other is under the hood like a regular cj, except that the m38 also came with a detachable box that the battery sits in under the hood

    Andrew,
    It is not possible to give an exact identification from the pics you took.
    However we can definitely narrow it down to 1949 CJ-2A or 1949 CJ,3A through 1965 CJ-3B.

    Not all frames had a serial number stamped upon them.
    IF this frame has a serial number it will most likely be located on the right top frame flange.
    Look just above the front spring pivot bracket behind the battery tray.
    Sometimes these frames were also stamped just foreward of the right rear U shackle bracket.
    In the absence of a serial number most frames can still be narrowed down to a certain time line.
    If you can take specific pics or provide specific detail I can give you a positive identification.

    Specifics of identification are detailed here:
    http://www.film.queensu.ca/cJ3B/Dati...ingFrames.html
    Let me know if you need me to clarify or explain the differences.

    I have a personal opinion concerning which specific frames were the best for 80" wheelbased jeeps.
    But the fact remains that there are only minor differences from 1949 through 1965.

    It is likely an excellent candidate for your build depending of course on your project details.
