Hi Roy,
you might be able to get one of the manufacturers to sell you their removable tunnel and adapt it. My ERA has a removable tunnel. Several other cars do too... Also, you might be able to gain some more room up under the dash to fit a fire extinguisher too - if you needed to.

PhotoGuy's (Alan's Arntz/Butler) is removable and he ended up making a few mods and added some nice insulation as well. What you might consider is saving the original one, keep it in tact, and make complete new tunnel from scratch. Any good interior shop could make or duplicate the top cover. Also, if you needed or wanted to move / adjust your shifter location fore/aft or side to side, this would be a good time to do it. See Ya. Good Luck.
