Since the angles of four of my 7/8 and 3/4 inch OD tubes attached to 
the fire wall are near perpendicular it is impractical to use the 
traditional methods of using a tube with a bolt in it. This is an alternative
I am considering. Four 1/4 inch AN bolts or socket head cap screws
with a similar .063 thick 4130  plate on the back side of the ss/fiberglass 
laminated plywood fire wall. A lot of little gussets to weld on.
Should distribute the load better into the relatively soft composite
firewall.

Vance what do you think? 

Anybody?
