Trying to make this a reality... So far I have the following information on the original Canadian 16" wheel:
Rim Size: 16"
Width: To be determined...
Backspace: 4-7/8
Bolt Pattern: 10 x 7.25"
Flange thickness: 19/64" chamfered for wheel nuts.
Hub wheel Studs: 9/16"-18
Bolt hole: 19/32" straight cut.
Pilot Hole: 4.75"
Joining bolts: (8) 7/8-14 UNF
Backspace: 4-7/8”
Outer half: 3-15/16"
The new wheel (minus the stem valve protector) would have different backspaces front and rear and be wider (at least 8") to fit the U.S. spec. 1.5 trucks...
