I scrounge tires from other shops take offs and have dozens of sizes in my storage area---only thing now the modern tire shops won't mount them for me because some are over 10 years old----


I like the mock up axles I described as it lets me configure many issues as I build--


I didn't mention in yesterdays posts that I use a hole saw with the INSIDE diameter the same as wheel center hole to cut end of board back about an inch(depth of saw) to center the wheel. The 6 x 6 altho a little heavy, allows me to easily lag bolt the wheel on with some washers . And is a good positive way of guaranteeing the frame/axle desired clearance -------you can easily just add pieces of wood to simulate the travel for choosing shocks and springs-


The 3 inch drive shaft tube mock up allows placement of the traction bars, torque arms, coil over mounts that lets me fiqure exactly where I want them before doing the rear end-that way the rear axle housing can be built with the bearing ends being the last thing welded so as to eliminate all the movement during the welding fab work.


Got to dig back in storage unit to get these out for pics but hope your getting the idea
