Difference in AD Chevy and AD GMC Cab - The 1947 - Present Chevrolet & GMC Truck Message Board Network

68GMCCamperSpecial · 02-29-2012, 01:17 PM

I have a 1949 Chevy 3100 with a pretty rough cab. I have found a GMC with a much better cab. Are they the same except for the grill and some trim? Also, will the fenders interchange?
Any help will be appreciated.

Front lip of the hood is different too!

Thanks. Is that the only difference?

The GMC and Chevys of 55-59 each have an entirely different dash. the AD trucks may be similar. The cabs should interchange regardless of dash differences

Ad cabs are the same from 47-53. 54 and up they changed the dash.

I'm not sure of the year change, but the earliest cabs in the 47-53 group had a driver side cowl vent door, and beside the dash change in 54, they also went to one piece windshields.

Thank you all. I appreciate the information.

The cabs them selves will swap without a problem. There is some difference in the trim and the dash but I think you can easily change out the trim to have Chevy trim. The Gauges are a bit different as the GMC has a higher reading oil pressure gauge.

I'm pretty sure that the 47/53 fenders will interchange except that some models of GMC's have a park light below the headlight. This may just take filing in the holes or leaving the park lights in place.

The radiator supports are quite a bit different and won't interchange nor will the hood latch panels.

Inner fenders are also different, my 50 chevy has a passenger side door lock only, my 3 gmc cabs are drivers only locks. Not sure if it was an option or what. Big trucks have the same cab as the 1/2 tons except the cab overs. There is a difference in the filler rubber between the cab and running boards between years also.
