Adrian, I would take a close look at the rear bumper mounts. I'm thinking
a 2x3 box beam with a couple short pieces to space the beam out from the
rear metalwork and a handful of long bolts.
That's how it would work on a TR6, anyway. Your TR4 may be different,
however, but the bumper mounts would be plenty robust for this task.
