So im going to buy this 94.5 PSD next week. its a Reg cab long bed, 5 speed with 120,000 miles on it. And the only part that sucks is its a 250 so its the gay TTB. BUT! one of my good buddies has a D60 sitting next to his garage that im going to buy off of him. So now to my question, this thing is going to be my DD, and i plan on running 35's. should i get a 4 or 6 inch skyjacker?
