The day i would be able to make one of these tops, i can honestly say that it would be at least $1,000... Although i may have the skill do eventually make something like that, the justified price would be outrageous because my materials and labor would be hundreds of dollars on it's own. One of the con's of being the little man, you don't have a shop in Korea to mass produce it all. But the statement stands, you get what you pay for, and sometimes you get lucky.
I have no guarantee's for Speed' SUT tops but the least i can do is look and see how i can help his fitment issues out.
