Everything said is true about the box; it's generic. There is a small picture of the '63 Lincoln on the box end. 1964 is the first year AMT made unique boxes for each model. So, 1958 through 1963 AMT annual boxes had these themes; Hardtop, Convertible, Truck and Compacts. The picture on top of the box didn't really tell you anything about the contents except; Stock, Custom and Racing (or another theme like Presidential Limo on the Lincoln). The only exception I know is the 1960 El Camino. Probably somebody else remembers another. No 2dr Lincolns in 1963, real or kit.
This topic has gravitated to an interesting question; where did the '67-69 Barracuda tool originate. Like the '67 Chevy Fleetside, it started in an AMT box and resurfaced in 1968 in a MPC box. To the casual observer, the part count and details seem the same in the 1967 AMT and the 1968 MPC. I am not sure it is the same tool, but it could be.
It is worth noting that the supercharger parts are in the Del Rio kit. Interestingly, the supercharger parts are not mentioned in the directions. Anybody got an exploded view of the blower? I want to use it!
I am guessing the original '69 Barracuda had a HEMI and slant six, and now it has a wedge 383? My feeling is that you will never see an all new kit from Round2, or a heavily modified reissue. Retro boxes and restored parts are about what I expect.
