Have an old rear wheel with a Suntour Accushift 6 spd freewheel.
1) Will a Shimano 7spd Megarange (13-34) fit?
2) Any chance a Shimano triple road rear derailer will work (considering the 34 tooth sprocket)?
3) If no to 2), I have a Tourney MegaRange, adapter claw version, handy - will this work on a dropout with a derailer hanger, or will that get in the way?

Yes, and if you use a Shimano rear derailer, it will most likely index OK with a SunTour _6_-speed shifter! (The Shimano/SunTour mismatch cancels out the 6-speed/7-speed mismatch.)

Nope.

1) most likely. You can add a washer under the right side locknut if necessary. 2) If it's long enough, sure. 3) If you can unbolt the adapter, sure. If the 'claw' is rivetted then I'd get a different changer.
Since six speed Accushift is evenly spaced, unlike other Suntour systems, this all sounds reasonable. If it isn't great, just get a six speed top shifter ($9.95 with cable) .
