bad day: Willwood drag brakes ( rear ) hat is only set up for 1/2 studs.
I call them, tell them i ordered it for 5/8 studs and gave them my axle register info, hat register is much larger.

They tell me they dont make a hat with 5/8 studs, have to be drilled.
I ask what bit to use to have correct tolerances- they don"t know>
Ask about the register issues- they don't know, its a universal hat.

I wait an hour, call back, i'm told you cannot drill the hats and they don't make any for 5/8 studs and dont know why a 5/8 stud has a 11/16 shank anyway.

Idiots!!

Weld wheels- ordered for 5/8 studs.
What do i get, rims for 1/2 inch, what am I told- drill them.
Idiots!

why place an order , take my order and not say anything?

Will never purchase anything else from Willwood or Weld again- EVER.

So, I
drill one hat to 11/16 knowing dang well its not going to allow enough clearance and, sure enough, too tight.
Done on drill press/centered- but axle stud locating just isn't that accurate .
Anyone know what size bit is proper to drill these stupid things and not have them sloppy ?

Thanks,
One mad Texan.
