Uhhh.... I can suggest a few things to him... Like the backing plate modification, and possibly not putting holes in the center for the silver button so 74+ cars would match better.
I've talked to him before, and he said that it was more of a hassle than he really wanted to deal with. That there was a lot of interest, but when it came to people actually shelling out for the kit, they got cold feet. The last dozen or so of the last run of kits were sold off at a pretty steep discount (read: at a loss). Not a good way for a business to stay in business...
But if people keep asking him, who knows? Maybe he'll have another run made up. But I wouldn't be surprised if the price goes up, as he will likely have to find another shop to have the metal cut... Some of the stories about the last place were - - - uhm, interesting.
