Talked to Jack. He doesn't know at the moment if there's anywhere local he can find a junkyard or broken Tcase but he'll keep his eye out. In the meantime if anybody has a broken one to send to him he'll tear into it. And of course trannys are always welcome if anybody wants him to look at a 6MT.
One question he had is what's the policy on this forum for shop owners to come in here and gather info as a private individual without paying a vendor fee? He said he'd register and discuss it here if he can do it for free until it's time to actually sell a product.
