10A=build date which is october A= first week. My code book doesnt say what the 4-2 is so thats one thing im not sure of.
style 64 means its a 64. the first 2 means its pontiac divison. the second 2 means its a lemans. the 37 means its a hardtop sports coupe. Body I am not sure of here is what my code book says. Assembly Plant where car was built Baltimore=BA Fremont=FE Kansas City=KC Pontiac=PO. but the body number is the production serial number of the body. trim isnt a ponitac code. my code book says Trim number indicates the trim color and material for the car. Black vinyl is code 214. dark blue vinyl is code 215. Saddle vinyl is code 216. Dark Aqua vinyl is code 217. Medium red vinyl is code 218. And Parchment vinyl code is 219. my book for paint code says indicates the exterior paint color and vinyl top or convertible top color if the vehicle is so equipped. A two digit ocde indicates the bottom and top colors respectively. Color starlight black=A. Cameo Ivory=C. Silvermist Gray Metallic=D. Yorktown Blue Metallic=F. Skyline blue= H. pinehurst Green metallic=J. Marimba red metallic=L. Sunfire red metallic=N. Aquamarine metallic=P. Gulfstream Aqua metallic=Q. Alamo Beige=R. Saddle Bronze metallic=S. Grenadier Red=V. and Nocturne Blue metallic=W.. not sure of what the ACC A49 B90 2073 is for the only other info that my code book shows is vinyl top color as Ivory=1 or black=2. I also can identify VIN codes,engine numbers, engine suffix codes, rear axle codes,transmission codes, month codes, Day codes, and tempest Le Mans group option codes. along with all other factory stock options. All this info came from Cars&parts magazine. catalog of Pontiac GTO ID Numbers 1964-74. matching numbers series. it can decode VIN tags, Body plates, Engine Numbers, and paint and trim codes. it was destributed by Motorbooks International publishers & wholesalers. hope this is of great help
