So I goofed and ordered the wrong gasket for my TR.  I have  an ancient Weiand with three bolts on the top plate.  Gasket has four.

It's 16.5" x 7.25" with four holes.  Meant for a Weiand Hi-Ram.  It's not worth sending back plus I've already opened the package.  Shoot me your address and I'll send it out.
