    OK, I think I know the answer after too much time looking around the web, but need to hear it from the experts. I have a '36 Chevy Truck, but I need to know which frame it has, as it seems they were changed mid-year. Can't go by the cab, 'cause it's a '37. It looks to me that the late '36 & newer have a distinct downward curve to the front frame rails, which makes the forged spring hanger/bumper bracket angle back upward. Mine seems to have a little flatter front rails, & the forged bracket sticks out fairly level. Also, the inside lower frame rails where the engine sits, are not parallel with the upper part of the C channel. If that makes sense. i.e.: If you were to box the frame rails, you would need to trim off a bunch on the bottom of the frame. So, I'm guessing it's an early '36, which makes it the same as '34-'35?
    Front suspension is gone, & I'm considering the Speedway dropped tube axle w/ parallel leafs. Is 6" dropped axle too much for running full fenders?

    I'll try to put some this evening. It's a long process of using my wife's phone & computer. My flip phone & old PC don't lend themselves very well to picture posting.

    Didn't get to the shop, so found these on the web. First pic is what I think the late '36 - '38 (low cab) looks like. Is this correct? attn: @cshades The front spring hanger/bumper mount angles upward & the tops of the frame rails seem to angle down more. Which makes sense so the bumper bolts at the correct height.
    Second is what mine looks like, which I assume is '34 - early '36 (high cab). hanger/bumper mount is shorter, doesn't angle up, frame rails seem a little flatter, & lower part of the "C" channel on the frame rails flairs in toward the engine.

    My 1936 low cab frame looks like the 2nd picture. The running board brackets have an extra curve on them and the front frame horns are straight...

    This may help, I can't find anything on the high cab frames, but suspect this is a comparison between high cab and low cabs.

  9. As far as I have ever known, both high and low cab 36s shared the same frame design. Chevy /GMC changed frame design in 37, the first pic is a 37 -38 and the second is 36. The 36 Low Cab was a half year only cab, they didn't redesign the frame for that. Should be the same basically 34-36. I have had my 36 for over 40 years and have done a ton of looking at others,, just my 2 cents. Mitch

    @Fishstik @Joe H @mitch 36 Thank you! These are the answers I was looking for. I was misinformed, I guess. That diagram shows exactly what I was trying to explain with words, that may not have been as clear as they could have been. After doing extensive web searching, & coming up with less than stellar answers, I knew you guys would have the info. I did see one place listed their '34 MII front kits as different than '35-'36, so that also made me wonder how many different frames were used in those years. Anybody know thew stock front track width? And the spring length? Mine is missing the rear spring hangers on the front, as it had an old IFS (60's) installed.
     
  11. I wish I could help you there, years ago, much to my dismay, I axed the leafs and I beam and installed one of those new fangled front suspensions we're never to speak about. I'll look in the spec book I have hidden somewhere and see if I can come up with the front track width. As for the spring, just figure your wheel base and find some front springs from an early Chevy truck that has the center pins in the right location, rebuild them and fab up some rear hangers. As for the axle, all the way up to 54 Chevy 1/2 ton will work. Mitch

  12. 1, looked in a couple places and can find the front track measurement. I know there are a couple guys on here with 36 stickers so maybe one will chime in. If you plan on using a FORD axle/ parallel leaf setup under her, you shouldn't have any issues going full fendered. Good luck, Mitch.

    The spring mounts on my 36 frame are 35 3/8" center hole to center hole.

    The center pin on my unloaded worn out spring is 17" measuring from the center of the front spring eye to the center of the pin hole.

    Center eylet to eylet on unloaded spring is 35 5/8

    Jim Carter has reproduction front springs, or Posies has 3" drop superslide springs available for a 36. Rear spring mounts for the front should be easy to fab up or you might be able to use the more common 47-54 chevy brackets. I believe the rear spring bolt is the same from 35 to 54
