Well, looks like a bit of Stony Ground there !
My experiences with the Shut Panels might then be of some use to others.
I would suggest that these should be bought bare and untrimmed - mine were in alloy (maybe they all are) and came from BAS in Wales. I had previously asked elsewhere and everyone wanted to sell me versions that were already trimmed.
Their shape and fit are
so dependent on where everything else around them ends up that I don't see how you can get their forms right and optimised until you know how the wheel-arch panels fit, and where the door cards will lie once the doors are fitted and the locks adjusted etc
I actually had them trimmed by BAS, as the car was there for the hood, which meant I had all the surrounding components trimmed and fitted
before I completed the Shut Panels, which makes it possible to tweak their shape, edges, bends etc to perfection.
I don't like the standard original shape of the Shut Panel up by the hood pivot, as I feel it looks like they didn't know what to do with it, especially on my car which has no hard-top brackets, so I changed the way it fits by bending it - prior to trimming - into the gap between the hood frame and the door pillar ; non-original but to my eyes it sits more elegantly, and is stiffer.
The vertical strips of the standard Shut Panels are constantly exposed to being bent by ones hips upon exiting the car, in my experience, and the sharp-edges of this single-thickness edge mean the vinyl trim lasts about 5 minutes before being nicked and split.
We folded these thin channels up from 1mm alloy sheet, and then Jack at BAS glued and slid them over the edge when he trimmed them - so there is now a rounded 3mm-thick section on the upright, which a) stops it getting dented and b) means the vinyl is less prone to hip-damage.
(These pictures are with 5.000 + km on the interior, hence some traces on these parts already, sniff)
Note also the MX5-type sound perforations in the wing panels where the rear-tweeters are hidden, again thanks to BAS.
PS. All the mods on my car are destined to withstand it being used, a novel idea to some, but you'd have to be pretty clued-up to spot (and a Johnny-No-Mates to criticise) the rare tell-tale signs that this is not original.
There's a free spare pair of edge-trims to the first Forum contributor that asks for them via PM, some limitations may apply ; you have to be 100+ posts, have contributed useful stuff, not just dithyrambic bar-room conjecture and, and you must use your car !
and now have found a fhc xk 140
