    I'm usually the biggest naysayer for frame swaps, due to the fact that they usually look like total crap.

    However, I am always looking for a good way to incorporate late model stuff to old bodies.

    I was at a light tonight and an older Ford Ranger was sitting next to us and I told the wife that ot looked about the same size as my 36 pickup. I went home and looked it up and it was 1/2" shorter. That would be negligible. Curb weight is about the same as a 35-40 Ford. Track width is the only thing I think might be wonky.

    1936 Ford
    Front Track : 55.5 in | 1410 mm.
    Rear Track : 58.3 in | 1480 mm.

    Ford Ranger
    Front Tread Width 58.6 +3.1"
    Rear Tread Width 57.3 -1.00"

    Check out the 6' bed single cab, 1998-2011.
    They are really plentiful around here. I have a bunch of cabs and spare parts laying around.

    Anyone tried this?

    The ‘98+ coil spring rangers are the only ones that I would consider as the TIB models you probably won’t get low enough without major $$$. I don’t know if DJM is still making drop beams but even if they are, they are spendy.

    however 3” of track width in the frame might be hard to hide.

    Ian Russel subbed a front half of a ranger frame and suspension under his buddies 46-48 Ford coupe . Then put parallel leaf springs kit under the rear .

    I defionitely wouldn't cut the chassis. My thought process is swapping it to get the late model drivetrain, along with a modern fuel tank etc. I have always wanted a 4WD 35-36 pickup. Not a monster truck, just something that looked originbal, but with a modern drivetrain. Something I could run to the landfill in. You love out in the sticks, you know how much you use a truck. My old 2002 is getting a little tired these days.

  6. There was actually a kit or a company doing this at one time.They made a slightly extended fiberglass '36 cab. Guy here locally had one for a while. I never got a chance to look at it up close, so now idea how well it all worked

    Yes that is the ‘98-11 I said to use. DJM dream beams are $500 per a set for the older models.

    I have the '98-'11 Ranger chassis under my '56 F-100. Let me know if you need any details off it.

    If you are thinking 4x4, you may want to check the track width of a 4x4 chassis. Its probably a different width then a rear drive chassis (could be better, or worse)!

    A 3" wider track width will put the outside edge of the front tire right at the edge of the fender opening. Wider fenders could correct that, but it may also be possible to gain some additional clearance with different backspacing, and wheel width, on the front wheels. The track listed width is made with whatever the standard wheel width and offset the frame was designed for. Often the track width of optional offered wheel widths & offsets is not considered in the listed track width.

    Another thing, that 1" narrower rear track width may put the inside of the rear tires against the bed side, or frame rail. Many old pickups don't have a lot of clearance between the inside of the tire sidewall and the bed/frame.
