I started his yesterday. Planning to do my first rat rod with it but it will be in a transition to a nice truck. I was thinking about using a Caddy parts pack motor, or the hot rod flathead motor from the 50 Ford P/Ub but i'm going to use the hot rod version flathead four that came with the kit. It sits to high and needs to be lowered. I can handle the front but I'm at a loos how to lower the rear so far. I'd welcome any ideas about this.
