Folks, please don't use aluminum panels. The edge of that
panel can act like a knife in an accident (and yes, this has
happened and lets skip the gory details). For this reason
I believe most manufacturers have gone to a glass panel
with a molded flange. Its easy to make one of these; you
can use the old one to make a mold if you don't want to
buy one from AMS.

Be safe out there,
Best Regards, Dave
