I would hold out for factory pedals. If you're going to use a hydraulic clutch, the pedal assembly incorporates some small braces that double as mount studs for the master cylinder.
Fwiw, your 91 will have dimples on the firewall marking the spots to drill for those braces and also for the bigger hole the pedal push rod goes through. The trans tunnel will have an imprint of the 4 spd hole and boot plate so you can see exactly where to cut.
Also, with respect to the driveshafts, I'm pretty sure that if you find a long tailshaft, 32 spline 4 spd and a 241 adapter (not sure if a 208 version will work) your transfer case will remain in it's current position allowing you to reuse your existing shafts.
