I guess if I didn't already have around 10 of these kits already I would be more excited. The nice thing is that this kits can be combined with the Modelhaus 1957 and 1958 Ford cabs which drop right on.
The parts that AITM sells/sold were the wooden spoke wheels, hood, and chain guard covers to back date the AC to 1917-1919. You have to contact Dave via his email on his site for info and prices. I think the same applies to the Peterbilt 351 conversion that our own Tim Ahlborn mastered for him.
One thing to remember about Hobby Lobby is that you can sign up for their e-mails and every one has a 40% coupon. Twice last year our local HL put out their own e-mail announcements with 50% coupons. Can't beat that. My local hobby shop has a tremendous model department, along with trains, die casts, military, and even doll houses, and their everyday prices are 20% off list for everything they sell. From time to time they also have old model collections that they sell for customers. Have picked up a number of great old kits at cheap prices.
