OK here are the pictures I promised, sorry for being late but I was in "The Odd Couple" play this weekend - what a gas. Notice in the "Seal Inner Brace" pictures, the seal comes with a inner tube to help hold and keep the gasket together. Took less than 10 minutes to get in on and light tapping with soft-face rubber mallet to make sure it seated 100%.
It will be a job for me to remove the glue from the other side, took 15 minutes to clean a 12" section.
