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?
