I probably have the tracings on paper already.
I do this from time to time for people making brackets.
as UD said.
1/2" plate is fine for torching the front.
the lower strap that goes from the foot over to the underside of the trans can also be torched out of plate.. but 3/8 is fine for the main strap and 1/4 for the lil tie strap.
i'll check when get home.. but am almost certain I saw the last set of papers from one I traced a few weeks ago.
