Anyone interested in 83 Pace Arrow Tear down and Rebuild?

Sometimes, what I am trying to portray in my head, doesn't always make it on "paper", like I think it should.

In case I didn't get it across properly, this is what I was trying to say concerning trimming the insulation after gluing it in place.

Hopefully, this makes sense. I could not do this with a normal utility knife, as the blade is not long enough.
