Fiberglass parts - boot / doors

[Knudsen]

Well, the fiberglas hatch has its benefits. Its lighter than stock and it doesnt rust.

BUT!
You can not use the lock. The fiber hatches i have seen, isnt strong enough to support the locking mecanism - you have to use those rubber straps (or something similar).
It isnt strong enough to hold the dampers, that means the hatch wont stay open by itself.
You can not (as far as i know) use the original rear window (no defogger).

If the car is for street-use, i would start looking after a stock hatch.
