Great Dave, thank you.
Is the fire wall a bolt in panel?
Yes, but it's sealed in too - with sealant in the overlap. In the interests of science (
) I unbolted it and gave it a few taps but it wasn't coming easily. I got a jemmy under an edge but I was bending it, so I gave up. (Probably needs a bit of heat to loosen the sealant - though it might be intumescent
)
There's a special sealed piece where the loom goes through in the passenger lower corner - they must fit the loom first, then the panel.
The obvious other conclusion is of course that a different bulkhead panel would make the shell LHD......
Remind me to get you a photo of the climatronic unit - It's only held in with four bolts - but two of them are well hidden. I made a mess of the padding/fireproofing piece on the engine side of the bulkhead - (behind brake lines etc) trying to get it out.
