I don't want to clutter the boards with a post for every question so I figured I would ask them all in one shot.
1. Who here as shortened their frame?
2. Who is running a street legal fuel cell?
3. Is it worth the money to swap my np203 to a np205?
1. I haven't done it yet, but I am going to shorten a frame, it's not an easy job if you want to do it right, you need to have it pretty level, and you need to take a lot of measurements, and references before you cut, and then when you weld, and you need to put fish plates to reinforce over the cut.
The best way to cut is a Z cut but most do a straight cut.
I had a thread saved that was very well documented, but lost my computer since.
I am still trying to find it, the guy had shortened a 72 chevy long bed frame to make it a short bed frame.
Unless you were talking about just the rear overhang, then yes I have done this.
2. I don't care for fuel cell so can't help you there.
3. If your 203 is busted yes, if not no.
I think yours just needs adjustment:
take of the rods from the shifter, align the tabs on the Tcase and put a pin in the hole to keep them aligned, put the shifter in neutral ( you might need someone to hold it in place, then thread the rods in or out until they lign up and reattach. everything should be smooth unless there is something broken inside.
