I got my tripod rear motor mount done and powdered coated.
Great! It did not fit for some strange reason. It fit when
I got done welding it but I had to move the engine up
an inch to fit the cowl so for some strange reason my tripod
rear mount no longer fit. It was about a 1/4 inch off.

Paul - it stress relieved in the heat of the powder coat "melting"
oven.  This is to be expected.   Welded structures can be a
pain in the butt some times, but are generally easy to make and
fairly forgiving in overstress situations if properly welded.
It probably should have been torch heated (rosebud) over the whole
unit while still in the jig, trying to get it all up pretty hot at the same
time, and making *darn* sure there are no drafts.  You can
really mess this up with a draft when very hot - sudden hardening
which takes away a lot of the necessary ductility.

Maybe but I don't think so. There is a straight tube from firewall
to rubber bushing hole in the rear mount tripod. See the sketch below.
More likely I made a mistake  when I repositioned the main tripods which 
are more like equilateral angle tripods. These will be way more sensitive 
to minor angular changes as far as the effect on height changes or,
in this case, the distance from the firewall to the main motor
mount rubber bushing holes.
