Gary - To follow up on
Dave's point, here are a couple of photos of
Mister Towed's set up.
Obviously no offence intended if you have already thought of this.
I just remember having to cut off the seat belt mounts that Gary fitted for me as they stopped the body shell fitting.
Good luck, Paul.
PS
I know you have been working on this for a long time, but it is a lovely nut & bolt restoration job, which always takes longer.
