JumperAndSon Posted October 31, 2012 Share Posted October 31, 2012 ...between a 1954 GMC and a 1955 1st Series GMC because I'm starting to suspect that my pickup truck is a '55 1st series rather than a '54 like I thought it was but I don't know for sure. So does anyone know how to tell? Maybe the serial number or something like that? Because if it is a '55 then it's really rare and I don't wanna go customizing it.I do know that it's a 1 ton, deluxe cab, long bed, with a 248 six cylinder, and hydramatic transmission.What makes me think that it's a '55 is that my buddy has a '54 one ton just like it and it has a different dashboard, and my dash is different from any other '47-'54 GMC that I've ever seen. But I dunno. So if anyone can help me out with this, that'd be great Ben Quote Link to comment https://www.bigmacktrucks.com/topic/28062-does-anyone-know-how-to-tell-the-difference/ Share on other sites More sharing options...
JTFormula Posted October 31, 2012 Share Posted October 31, 2012 On the trim tag there should be a build date with a letter and a number. Or if you can get a picture of the tag I can check it out for you. It should be mounted under the hood.

41chevy Posted November 9, 2012 Share Posted November 9, 2012 The doors are the same. The hoods interchange but have different emblems in different locations. The front bumper is the same. The running boards and cab filler panels are the same. The back and corner glass is the same. The seat is the same. Just about EVERYTHING else is different.Cab: 1 piece curved windshield glass slightly different arc than 54, cab roof peak smoothed out some.Completely different dash, different gauges, different knobsFrame: different kick up in the rear, lower and flatter for the bed. Change to bell housing cross member to accomodate hydramatic trans which debuted in '54.Bed: 2" deeper, flat tops, ribbed sides by the fenders, tailgate and tail lights change. It is more of a second series bed.Front fenders: Recesses for marker lights, shorter front "overhang" where it meets the bumper.Front grill: completely differentFront apron: shaped to match different grillOpen driveline:(drive shaft) 55 on series 1, 54 is a torque tube235 / 248 /261 6 cylinders from 54 up with Hydramatic have a 60 psi oil pressure gaugeMost of this is from a 1955 G.M. Tech Bulletin. Dash and open drive shaft are the 2 biggest noticeable differences.

JumperAndSon Posted November 14, 2012 Author Share Posted November 14, 2012 I may have now How much are you looking for??Well I may be crazy, but once it's running, driving, stopping and steering, I was thinking somewhere in the $1900 area. It's only got like 34,000 miles on it and everything works and stuff, it's just kinda rusty.Ben Quote Link to comment https://www.bigmacktrucks.com/topic/28062-does-anyone-know-how-to-tell-the-difference/#findComment-145957 Share on other sites More sharing options...
