I use an air powered Die Grinder to knock down the bumps
and high spots..it eats thru it like it is butter
I had to customize the handle to open the door and the
handle to roll the window down..
a little resin in a few low spots...a little bondo and a sanding
and it will be ready for the spray
I am guite happy with the fit...it should make a good sounding front stage.. there should be enough airspace to produce decent mid bass
