Brad lives just a few miles from me, and has been a HUGE help with my endeavors on the TR8. In fact, I just came from his house after a quick drive with him to check some of my work.
Of course, I can't speak to any issues with unanswered or bounce-back emails, but you can always call him - phone numbers are on his website - even his cell phone. I've always been able to reach him.
I asked him about his cutting back, and he said he's going through a bit of burn-out. His mission has been to locate hard-to-get items such as trim pieces. If they're not available, he's gone so far as to have some made. The most recent are the four heater/fresh air control knobs. I have a set of them, and they look very nice - not exactly like the originals, but then, what resto parts are! He still has plenty in stock, by the way, if anyone needs 'em. But I don't think he's had the response to some of his efforts that he had hoped, and that has contributed to his burnout.
He's in the process of cutting back on some of his rolling stock - his silver TR7/8 is on ebay now. He has several others, in various conditions, and is thinking about cutting down to just one, and concentrating on other projects.
Send him an email - address is also on his website -
