I used David Beaumont, albeit a few years back now. Good service and a fine recon box. http://www.4x4gearboxes.co.uk/index.htm

My son had one in his 110 hardtop, it was mounted at the rear rh side on the wheel arch right at the back with the exhaust coming down behind the rear wheel. Worked well inside the vehicle, the ony problem was that after once some paticularly vigorous off-roading the exhaust had to be cleaned out to remove all the excess mud that was blocking it.

If you've checked everything else, it sounds like an airlock in the heater matrix to me.

When I take the truck cab off my 88" SIII, the top fixing of non-retractable seatbelts just goes through a convenient hole in the corner of front of the rear tub so the belt goes over my shoulder, it actually feels better than when it is mounted on the side of the cab.
