I am nude and so forgive me if it's not all right to respond to an old post like this. I had not seen any updates on the up and I'm very interested. I am building a 5130 100 and getting ready to purchase A rolling chassis for a C6 Corvette LS2. I have no idea how I'm going to do it but I intend to make it work. See you this link I was guided to buy another member on this site:

I am hoping that you have information and specifics on how years has worked out that will help me.
