From what I heard when MPC originally released the 1/25 General Lee they couldn't find the correct 1969 hood and interior bucket. It was released with a 1970 hood and a stock car interior bucket.
When MPC released the Charger 500 kit they found the correct 1969 hood. The 1969 hood tooling was misplaced again so the General Lee kept the 1970 hood.

When I built my MPC glue kit General Lee I located a 1969 hood from a Charger 500.
Here's my MPC glue kit General Lee I built last year with the 1969 hood and correct interior.IMG_7579 Small by Michael Scarola, on Flickr
