Now the fun really started. I laid a long piece of angle across the top of the core support to the top of the firewall, where the two rubber hood seals contact, and used that as a fixed point in space to measure the distance down to the base plate at several locations. Doing the same thing on the hood, across the seals, the distance from the fixed line to the hood underside was measured. Adding the two together gave me the space the foam needed to fill. If I measured it once I did it 30 times. Only going to get one shot at this as the length of foam was within an inch of what was needed. No mistakes or Moroso would be getting more of my money. The absolute toughest part of this whole ordeal was cutting angles in the foam. I used the sharpest implement I could find which turned out to be my wife's new wiz bang kitchen knife. She was P-0'd big time when she asked how I had cut the foam. Hell, I wasn't going to lie, she will get over it !??
3M weather strip adhesive was used to glue the foam to the base plate. I roughed up the plate with some 80 grit paper to give the glue something to grip to and commenced to join the two together. I then ran a seam of black silicon along the inside of the foam for S & G. Enjoy:
