Actually, the date on the build sheet seems to indicate that either it's a form number (it was "printed", not filled in by a computer printer or typewriter), or AMC typically filled orders two years in advance. Either one indicates that the 65 convert is just a 65 convert. I've never paid much attention to build sheets -- never found one in any of my cars (only owned 3 70s-80s, others mostly 65 or older -- haven't looked in the 68 American parts car though, and probably won't). It's interesting to see that AMC basically continued to use their old letter/number serial number system when cars were ordered. The letter was dropped and the six digits used on the VIN when the tag was created. "Z" for a Javelin, obviously. I wonder if the letter was just for body or also indicated engine size, or just engine size? That would take more research, and really wouldn't help anyone except those very few with build sheets for their cars. ------------------------------ Date: Monday, August 21, 2006 04:37 PM From: eddiestakes <eddiestakes@xxxxxxxxxxxxxxxxxxxx> On both those 65 Rambler Ambassador convertibles on ebay, I got back a nice email from both sellers. I am still confused as to what makes a regular production car a prototype. One mentioned the build sheet. But build sheets were printed well in advance of models. For instance here is a 71 AMX build sheet: http://www.planethoustonamx.com/parts/71amxbuildsheet.JPG It don't make it a 69 prototype anything, it still makes it one of 2054 made in 1971. So while there is a blog on there, which is neat, I am still either stumped or missing something? _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
