I guess converting it to LHD is what's next.
I cut out the foot boxes on both sides and made mirror image replacements.

It's not as wonky as it looks but there is some room for cleanup, which will have to wait till the glue dries.
With the revised cowl and firewall in place.

The opening for the steering is filled ready for putty and the wiper mounts are gone, but not filled yet.
The engine still fits, though I have no idea if the steering will clear the exhaust headers.
