Wilwood Low Profile Disc Brake Kit Help....

Yeah if your using stock axles ,with only green bearings,the difference between drum and rotor thickness is the only difference. They work great , but I have them all around with an adjustable prop valve and late model manual master. I had a big brake kit but it wouldn't fit inside my rear b.s. street lites
I'm installing a Moser fab 8.75 housing and axle package. I have the SS springs with Dr. Diffs offset hangers and poly bushings. Right now, with the snap ring against the housing end, I have about 3/16" between the tire and leaf spring (Weld S71 with Mickey 255 60 R15 ET Radials) and about 3/4" to the fender lip. I was thinking the 3/16" of the rotor thickness would be just about right?
