Hi Jim
I dont have any photos of the mods I did for the thermostat housing, but you can see the bump in the carpet behind my chassis brace in the attached pic
Its pretty easy to do, I just worked out where it was going to end up in the engine bay and then cut 2 slits with an angle grinder, then knocked it in so that area was completly reversed, then filled in & welded up the sides.
