Art you are going to open up a can of worms bro. Unless you get SUPER lucky the gas tank will be back against the bulkhead. So the tank will have to be removed. Then the stringers in the engine bay may need to be replaced so that they can go farther forward to the new bulkhead. I doubt that they should be extended.... Seat moving forward is probably not a big deal at all. Then the engine hatch will need to be extended and reglassed..... Sounds like my POS boat

I have to notch the bulkhead cause the blower motor won't fit, and the old seat was roughed on the back side, so yeah its going to be a pain but not as much as my legI need a bottle of jack and a bigger chop saw to just cut that phucken leg off so I can move on. still can't drive jon. well I'll call yah to night buddy. artimus is leaving the building.

So how is this project going?

Cut the glass off. Make sure you dry it for weeks in a warm building with a heater then use a moisture meter. When it is ready, have a professional reglass it. No big deal.
