Calling all fleetsides with 20's.....lets see em please

[towbar]

OK guys, this may have been run aground more than once but I searched and didn't find it so here I am. I'm trying to decide on which wheels to go with on my 72 fleetside shorty, going to do a 4/6 drop...maybe even 5/7 and I'm sure I want 20's all the way around. However I cant decide if I want Boss 338's, Coys, Torque Thrusts, Billet Specialties or something other than these. Help me out and post up some pics of what you're running.... any backspacing info you have would be great as well. Thanks for the help everyone!
