    if i remember right we built a truck using a ton and a half cab on a half ton ch***is. the whole nose had to be used from the half ton. i Think even the radiator support was different.
    i have a ton and a half truck here if you need measurements
     
  4. I'm pretty sure the front clips will swap if complete but I'm not 200% sure enough to spend someone else's money.

    What I need is a clean 1-1/2 ton front clip. I think

    Only the hood is a direct fit from cowl forward.

    Fenders have larger arches because of bigger wheels and tires.

    Maybe it depends on just what 'tonnage' truck the parts come from. But here is my experience. Some years ago I bought the 'front half' (ch***is cut off behind cab, got everything forward of that) '52 GMC. Don't recall the exact model number, but it was all Chev/GMC common style, steel wheels, etc., not a really heavy duty truck. What I found is that the fenders are wider, they rise up on the cowl farther and the hood sides are 'shorter' because of the taller fender line. Of course, the wheel openings are larger radius.

    I suspect there are about three versions of front sheet metal. Pickup size, next size up with same dimension hood/fenders, but for the wheel opening, and the larger truck type I described above, which is considerably different though not immediately apparent at a casual glance.

    The cab was essentially the same as a pickup but for minor floor differences around the transmission area. It did have the more m***ive grille, which was what I really wanted, not the cheap tin used on light duty versions.

    Yeah, I have a hood from a big GMC that I was hoping to use on my half ton. Significantly longer

    Many years ago an aquaintance with a small body shop told me how a customer of his had bouught two NOS front fenders for his 52 half ton pickup they were painting.
    Apparently they got everything painted and when they went to bolt them on they discovered that the fenders were for a ? one ton truck.
     
  13. Ok - so if I wanted the longer flatter hood and fenders that mounted higher which should I be hunting down?

    1-1/2 ton ?
    Larger ?

    Maybe Squirrel can answer that....I think he has a number of early parts manuals which should identify which truck models had the wider, higher mounted fenders with the shallower side hood.

    Not sure what you are up to, but trying to interpolate from your comments, you may end up using small truck fenders combined with sections of the larger version to achieve the goal.

    I posted a link to the parts book. i guess I have to read it for you, too? :)

    COMMERCIAL uses the small stuff. UTILITY uses the big stuff.

    To help dumb it down a bit, anything with 8 bolt wheels will be the same sheet metal as a 1/2 ton, you need to find something with 10 or 5 bolt wheels, which would be a 1 1/2 ton or 2 ton. I believe the 3 tons and bigger have a really wide and goofy looking fender.o_O

  18. I don't mind the s**** once in a while :)

    Thank you !
    I did look thru it, I didn't scour it thought. Looking thru-I wanted to see or find a diferentiation and what the different things were compared to each other. I didn't see that. However it may be there just not presented within my scope.

    Most manuals are developed with the ***umption that the subject is present, within range of physical observation. If I had the parts with clear markings and the numbers list I could tell if they were correct, per se.

    The way it works...the first picture I posted, of the truck, shows the GROUP numbers. You look in the manual for that GROUP, then look up the part numbers, based on model. The models are listed as COMM, UTIL, P***, etc. The second picture I posted is in the front of the manual, it lists the model and serial number information. Use that to translate the COMM, UTIL, etc listings to a specific model, such as 3800, 4100, etc.

    got it?
