Welcome Medicmax to THE BOLT.
Good to see another Islander here.
Unfortunately I dont know of an easy fix for your problem short of replacing the whole door.
And you are limited to the unique 51 doors w/pull down handles and wing vents.
If your good with a welder,how about scrounging up a junk door or one thats been hit and cut the patches from the inside of it.
Regards
P.S. Where abouts on L.I.
