Finally getting to it!!! 1970 Duster 340

I need to get an idea on what to put the Kmember and tranny on. I have seen some great dollys built and have no idea how to build one. I have a lift so the car is not the problem. I am doing it this way to replace my trans and do some front end work. I would need a dolly where one could remove the 727. I found this photo on this site and this dolly looks nice!
