the skylark kit with the box number 6566-150 is the repo,the only way you can rell is by the number,its hard to tell cause its indential so beware
Good to know. I did some searching and found #4031-100 for the original 1966 issue 'Craftsman series' which was a snap-together kit without engine. I have one I bought in the early 80's, #6566-150 on the box. It's the glue-together kit with engine. The Modified Stocker is #30147. Saw this on the 'Scalemates' website, released in the 1990's: https://www.scalemates.com/kits/all-american-models-1966-buick-skylark--1301433
