I've been spending my time trial fitting the new body panels recently.
For those that asked the bare GRP doors weigh a smidge over 4kg undressed.
Here's a side view with the door and wing on the O/S in the final location, I've had to cut the inner mounts for the wing front and rear and re-attach them once the wing was in the right location.
The door on the O/S needs some work too to smooth it in with the wing. The N/S door is much better and I wonder if it's my car not the wing/door that's a little wrong.
I'd been pondering how to mount the doors on the hinges, the normal doors have a "box" on the inside with a threaded plate behind. I ended up doing as follows;
Marked up and cleaned out the entrance point for the hinges and used a hold cutter to make the bolt holes. Once mounted the door seemed a little flimsy on just the GRP so some added some strengthening.
Cut and folded some internal braces
Cut a top plate, I had to pad underneath the lower hinge mount with some cut-fiber-filler
The plates had the A-post door face drilled and some more fiber filler was put on before they were bolted through the top plate and held in place, a further bolt was put through the A-post face to ensure they don't flex.
Placed the door back on but only using repair washers, I will make a plate for this purpose, I need to weld the nuts to the back of the hinges too.
