Tire & Wheel / Suspension set ups

[sandfreek]

Well Im finally back to working on the truck again...Got the K-member and the rear axel all welded up now... Im thinking of goin with a 17" Torque Thrust 2 or staying with a 15" wheel but need to know what springs I should go with to keep the ride good?? I put on the 2 1/2 drop spindles and had 3" drop springs but it almost sits on the ground with that set up... The rear i can do what ever since I have 5" springs and several drop blocks to choose from...

Pictures and set ups would be very helpfull as I dont know which I want to go with at this time... Oh and this is a 66 LWB 1/2 ton... Thanks Ron
