I have just acquired a 77 seirra stepside and need some informaion on the 4wd. I beleive it has a np203 tcase. Is this fulltime 4wd, as in 2wd is not available at all, and if so, what is the best gear for driving around town? Any help would be greatly appreciated.

if it hasnt been done already you can put manual lockouts on the front hubs and let them freewheel this way you can drive in 4 high and save a little on gas around town
