Wilwood conversion problem

Some good info here !! I was just going thru the catalog entertaining the idea of putting some Willwoods on my GTS ! I was going to do like I did with my /6 and get the SMP 15" Rallye wheels ! I guess that would throw another monkey wrench into the mess there is already ! Maybe I'll just stick with the heavier Kelsey-Hayes Disks, and eliminate any problems ! Really sucks that a company such as Willwood wouldn't stand behind their product, because I see no disclaimer in all the info I've read about the stock drum hubs and 9"-10" drums !!! Glad I read this when I did !!!
