As the Pup nears complete strip down to a bare shell my thoughts are starting to turn to bracing ready for working through the various major repairs (door frames for example). Question really is around what dimensions for the box section would be appropriate? 25mm by 25mm, or better still something like 30mm by 30mm? I'll need to be ingenious with how I do it and will likely go over the top just to make sure, but keen to brace it with something appropriate.
Thanks, Jamie
