It's that time to admit that I won't ever make this conversion. Bought these in early 2000, I was hoping to make the switch but it's not going to happen. These are the original set up with one of Doug's original cast and the other a modified and capped trio that retains the choke pocket. This is better for street us than racing as you probably know. $500 for the pair and shipping I gather to be around $100 unless a buyer has a better idea or is local to the MN area for pickup. I hope these go to a good car, my 65 Signet convertible is not going to be the one.
