randy's ring and pinion gets my vote

 

do the 81's really have 3.90's? I am building an 81 pickup now. I haven't been inside the axle's yet, but I don't have the $$ to regear yet. My 81 has a 4speed, well it did, just swapped a w56 5speed in it. By the way I'm new. I've been reading this forum faithfully for about a year now.
