Glad to here you are ok!! I have a friend in Long beach who still has to have permission to get into his area.
As for the front hatch, there is a thread with the excat mesurements, but it isn't going to be easy to make one!! Belive it or not they are a bit involved there are alot of angles to make.
But if you are handy and have the time to go slow you should be able to get it done.
Might be easier to make one out of wood and then use it as a mold, cover it with glass, and then go from there.
I found the thread that had the size
My hatch is missing, I got measurements off a 74 hatch, I hope they are close. They are:
Overall length front to back - 22 1/4"
Overall width - 25 7/8 "
back height- 2"
front Height- 1 1/2"
flange under teak - 1/2" x 18" long
Hope this helps.
Thanks
