Thanks mate!! What thickness for the bottom plate you reckon?? 1.2mm be ample??
Going a 75mm top pipe, and similar to clunk's photos, going to have a 50mm pipe coming from the bottom near the tow bar end, but bend it up and wrap it around all the way directly under the top tube but tapered in slightly to follow the top to bottom line of the car. With me?? lol
Hopefully it'll turn out ok!!!
