Welcome to the TT group. You'll enjoy your TriStar -- it was my first MC. I redid the carpet on mine. As has been mentioned, there are some threads here on that . . . and yes, you do need to carefully jack up the port and starboard consoles just a bit to get the walkthrough section out. I reinforced mine with some added glass cloth and resin. The sections have a plywood centre that's set in a fibreglass shell. The plywood can rot after a while.
