not me, a friend of mine is a laminator etc, he makes moulds fibreglass parts boats all sorts of stuff, if a fibreglass sliding door was sensible money I would think it may be a popular choice, £600 for a used one is a lot of cash, what other parts in fibreglass do you want? bumpers, cab doors perhaps ?
I will ask him, give me a few days. he would need to sell a few as I assume the mould will take a day to make.
I spotted that as well... I did wonder how well it would stand up to the force of slamming against the spring! There are companies selling bumpers, pedal trays roof parts http://www.riveria-roof-company.co.uk/ http://www.nomorerustybits.com/
Riviera seem to have disapeared and the rustybits folk only do bumpers and pedal trays. Bought and fitted a fibreglass slider to mine a number of years ago and it didnt quite work. Got shut of it - it wouldnt close properly and didnt have the time to fettle and a steel one came up. It looked bang tidy and in retrospect I think the issue was the mass of the thing just wasnt right. The weight of the door is a factor in how it shuts. Guess we should have added some roof lead (flashband style) under the door trim. It might have helped. should have persevered. Sold it a Vanfest for £50!
Just added my interior panel back on to my sliding door after having it off for a year and was amazed how much better the door closes with that little bit of extra weight - so think Dicky's suggestion of adding weight to a fibreglass one would be a good idea.
I recall from somewhere there are two setting on the sliding door spring, normal (hard to shut) and pansy... I've no way of substatiating that other than internet rumour, but if this is right the pansy setting may suit a fibreglass door?
The only GRP slider I've come across was broken at the middle hinge fixing. Not an easy fix for a welding type person.
