The incredible folding Cuda!

The good news is, if your floor is not level we can work with that.

Bad news is, you probably have to hang all the tin and square the car back up before you do any work.

Or maybe you already know how all this works. I don't know. If you need advice, i can help and walk you through it.
Feel free to PM me and we can chat on the phone. It easier to talk it through than type it all out.

I see a lot of string lines, jack stands, wedges and plumb bobs in your future.
