weve been working on these for a little over a month now. did our first official test fit on my highschool buddys car. really pumped on these. they will come with new plastic, springs, and pins, but since we don't have those in stock yet I used an old set for the test fit. these will work for all 55-61 GM cars. our first run will be 75 sets and weve already had 65 preordered. target price is 260 with polished hardware as shown. feslers offers an aluminum version of these for 220 so we wanted to be fairly competitive with them. I think we have the better product without a doubt. pictures don't do them justice. what do yall think?
