I found this a while back after I bought and sold the UMI bracket and hub kit.
I’m sure you know to drill the top spindle hole 1/4” or so deeper and clean up with the stock 12mm bottoming tap.

The UMI brackets didn’t require any spacers or washers. Maybe the note to add washers in the drawing I provided is to cover their butt.
I’m sure you know you can either cut the rotor off the stock hub or use the Wilwood aluminum hub.
The stock hub will require slightly longer studs to accommodate the extra thickness of the slip on rotor. Note: it will increase the track width .300” per side, not a big deal for most.
The Wilwood aluminum hubs will need 1/2-20 screw in studs to be purchased separately.
