Just so you know, there are two types of washers; type A with offset holes, and type B with centered holes.
Which washer you use, and which way you install it, depends on your bolt circle.

And this you probably know,but for those that might not;
The shank-nuts come in several lengths of shanks.Make sure yours don't bottom on the drums before tightening at the washers, and also make sure that there is plenty of shank to spread the drive-torque, and plenty of stud engaged.

yea, that`s why I said I`d have to cut the nuts down because the prostar nuts I have are too long. the two washers he sent are oblong but longer than the ones in the pics. The prostar nuts fill the holes very well, I think they`d work as is , w/ shortening. THE studs are 3" to start with, no problem there. I did some looking at them(mounted one) , and figured out that I can machine a wheel "bushing?', to exact fit the axle flange ring and the inner diameter of the wheel opening. After all that, I`m not sure it`s worth the trouble, for a 1/2" extra width on a perfect fitting wheel. I have exact spacers I made for the wrong offset prostars that I`m running. 275`s on one pair 295`s on another pair. not like I really need these things. 'SORRY FOR LONG POST" THANKS FOR THE INPUT.
