edavis par dosnt make a pro tunnel, just boards that fix the problem before it happens.
you are going to have few choices
van amburg maks one
cr racing makes one, and is coming out with a new version in two weeks
you can pony up some real coin and have one custom made by evans marine
fabcraft will do one if you call now and get on the list for the end of jan
or do a stock one that comes as a full assembly bulkhead, chaincase, and tunnel for 2200
i went with the cr racing one, its built with all holes predrilled no fuss. drop brackets pre drilled as well
i beleive the van amburg is the same way
