Mythbuster is pretty much long gone from the forums. There is no way in getting contact with him in any meaning.
I've always wondered about this: does that mean that all their stuff is free to use (respectfully) as long as you do attempt to contact and receive no answer, or does it mean that all their work dies with their leaving?
If you ask and don't receive an answer, then you should take it as a no it's like calling your mom to ask if you can order pizza would you really go ahead and order it if she doesn't pick up?
I think that as long as you're clear about what you updated and fixed, you're not doing anything illegitimate, as you're only adding "money" to the pile.
The Crown Victoria has always been my favorite vehicle. To see one in beam is amazing. Although, it is very dated, I wanted to still enjoy it. Here, it is on the Grand Marshal Frame with it's suspension, drivetrains, and with PBR.
I tried doing that a few months back and gave up in frustration, I do want to try making my own though
I dont know if its a real update. because that is FCV of Nadeox and his is released in russian website with name jhon tanner. I don't think he had the right to publish it except if Nadeox agrees
