The n/s door is in very good condition, but the o/s door, is not only rust but a very bad fit,. it has had a bottom replacement, and skin, but this has rusted out, and I think it was a Roadster door converted for the GT, which is a bad idea, because the latch mounting is recessed on the Roadster, so the latch will never be smooth.
Managed to get a nice second hand drivers door from the MG breakers yard in Chichester.
This is a good technique for removing a siezed hinge bolt.
In an attempt to get really good door gaps, I intend to build up gaps that are too large with 3mm round steel rod. I have cut away the door edge and will weld in the rod to give me a perfect door gap, this will be repeated in several places around the doors.
I cut a slot in the bottom of the door frame, starting near the front of the door and going just round the rear corner. I then clamped the door to close up the gap.
I welded the join in a few places and test fitted the door, once I was happy I seam welded the join fully. This pulled the bottom of the door in a couple of millimeters, just enough to improve the fit of the door.
Probably not very clear in this image, but the door gaps are now fairly even. I test fitted the new tailgate, very happy with it, I also fitted some new telescopic gas struts.
I sent the door latches away to have them re instated with Zinc plating and yellow chromate colouring, as per the original finish.
