fwiw a 2 inch spacer for a
1997 ranger (and other fords used to mention 97 ranger...link) fits a GC series. put a m10x1.5x50 bolt thru back (with loctite) and use a lugnut from a 2013 ford escape to fasten the spacer to the hub. then use the (usually) included open face lugnuts to fasten rim to hub.
so far...1 gc2400, 1 gc1710, 1 gc1723mb, and now 1 gc1725mb.
lot cheaper than massey spacers, they continue to use the lug studs. so with them behind axle plate you got almost 1" of bolt sticking through and only 1 clamp force. my way you have approx 1/4" on back of axle plate and 2 clamping forces for approx 100$ less than approved spacers.
