I cut off a 2 1/4'' length of an .063 2x2 1/2'' angle bracket for a gascolator bracket. I drilled bolt holes in the top for the bolts and the priming line. I then drilled a hole for the fitting thru the firewall. I drilled pilot holes in the bracket for riveting it to the firewall. I dimpled the #40 holes in the firewall and countersunk the matching holes in the bracket. I then primed this bracket.
