GMC Owners - VINs
Since there is very little info on GMC VINs out there, I was thinking that if we all sort of try and figure out the VINs as best we can with the info we have maybe we could come up with a fairly accurate VIN decode sheet on our own. And for those who don't have the books or info this here may help.
From the Factory Assembly Manual I have this is what it has for 1970: 1st character = Series Designation / Chassis Type C = 4 x 2 Conventional 10-60 Series G = 4 x 2 Forward Control body frame integral H = 4 x 2 Conventional 70-80 Series J = 6x 4 Conventional 70-80 Series K = 4 x 4 Conventional M = 6 x 4 Conventional 60 Series P = 4 x 2 Forward Control Conventional S = 4 x 2 Bus Chassis T = 4 x 2 Tilt Cab (Appears to be the same for Chevys) 2nd character = Engine Type E = V8 Gas M = V6 Gas S = 6 Cyl Gas V = V6 Detroit Diesel ( Also appears to be the same for Chevys) 3rd character = GVW Range 1 = 1/2 ton ( 3900-5800) 2 = 3/4 (5200-7500) 3 = 1 (6600-14,000) 4 = 1 1/2 (13,500-18,000) 5 = 2 (15,000-30,000) 6 = 2HD (19,000-45,000) 7 = (21,000-44,500) 8 = (23,000-48,500) 4th & 5th character = Model Type 02 = Flat Face cowl chassis only 03 = Cab - chassis 04-34 = Cab and pickup box (Mine) 05 = Panel body 06-16 = Suburban 09 = Cab (flat bed) 14 = Blazer 6th character = State Certification Hyphen = NONE K = PA (Z55) T = PA (Z74) 7th character = Assembly Plant A = Atlanta ( '71 changed to Lakewood ) B = Baltimore C = Southgate D = Atlanta GMAD ('71 changed to Doraville) F = Flint G = Framingham J = Janesville K = Kansas City ('71 changed to Leeds) L = Los Angeles ('71 changed to Van Nuys) N = Norwood P = GM Truck - Pontiac R = Arlington S = St. Louis T = Tarrytown U = Lordstown W = Willow Run Y = Wilmington Z = Fremont, BOP 1 = Oshawa 2 = Ste. Therese 8th character = Model Year 1970 = Z = 15 series, A = 25 - 35 series 9th-13th numbers are the Unit Numbers 1970 Starting with 50,001 This is all that I have on the VINs from the book like I said above. I hope someone else can add to this and/or correct any mistakes I have made. ![]() ![]()
