What do you think I should ask for it?

Hey, does that truck have the 8n 3/4 rear end, If so it may have 391s or 355s in it. It my even have the 489 case being its a 72.And if it has a sure grip the third could worth around $500 by it self. If so you may want to hang on to those and through in a peg leg with high gears. just a thought...
