I'll let you know how mine turn out. Got them yesterday. I'll be mounting them on my 63 4WD Frankentruck. After seeing oem4me's 4WD with 19.5's, I was smitten.
I widened the 16" that are on my 2WD and have done a few others.
I got a 4WD hub assembly off a newer truck and machined the center to mount on my brake lathe. I cut everything with a grinder and cutoff wheel mounted to the cross slide of the brake lathe. The bigger the diameter the more room to work.
How to mount the stock hubcap is the question of the day. All my spares are 7 5/8" clip style. 4WD's never came with hubcaps but dress them up so much when their installed.
Plenty of room to move the center portion from the 6" stock backset on the 22" transports to a 4 1/2 backset like the 16" wheels I did in the past.
Recouping from a triple bypass for now, but there's plenty of future ahead and some strategy thinking to do. lol
