The stock-car version is due in November and will represent Tim Flock's 1952 No. 91 car. The kit's being produced via a partnership between Moebius and Model King, and will be a limited release. The racing version will include all the racing components and decals, as well as parts to backdate the standard '53 car to '52 specifications.
I just bought two of the '53 kits and I've been itching to get started building!
