The thing is, delux, I have seen part of 1958GMCNut's kit he bought from Mar-K and know for a fact that he is impressed with it although he has not installed it yet...
When I saw JC's wood kit going for cheaper I had to wonder if similar quality was there for less money... however as you say it is NOT rocket science and I'm a heck of a lot better at wood work than I am mechanics so I hadn't ruled out just buying the wood and doing it myself... it was option #1 in my OP, remember?

lol
Thanks for your suggestions!
