Sunbeam Alpine 4 link suspension

[socorob]

Been seeing so many awesome rear link setups on this site. Now my leafs are worn out on the rear of my car. They are unavailable new, and if im pulling them apart, I would hate to get them rearched and go back with that setup. My car is a 1963 Sunbeam Alpine with a Ford V6, tremec T5, with a narrowed Ford 8 inch rear with a currie aluminum carrier with a 4.11 eaton true trac in it. I've autocrossed in it a couple of times, and I'd like to do more but my leaf springs are shot. I've looked at a lot of different setups and want to have something similar on my car. I lifted my car 2 or 3 times and took plenty of measurements and then started playing with one of the online suspension calculators. I think I have a setup that will work under my car, and was hoping some of you more knowledgable folks on here will tell me if my numbers look good and I'm going in the right direction. The car is 95% a street car with a little autocross and such. Thanks for any suggestions, ideas, criticism, etc.
