In reply to Hotbad Peteel:
well there isnt any fibreglass work needed realy, since its just cutting some away then glueing in new hatch.
the strenght is a serious issue though and in the end the reason is that im just to lazy with the packing through the small holes :0)
think i will do as u recomend and forget it, and spend the money on some new gear instead which packs easily through the hatches i got.
