9in ford help,tucking 18x12 budniks with 5.5 backspacing and 55in rearend?

[fillpot]

Guy's got a 9in small bearing ford rearend under my 69 camaro,g-linked,minitubed etc.Here's my problem from flange to flange the rear is 55in,i bought some 18x12 budniks from nathan on here a couple of weeks ago with 5.5 inches of backspacing,once I got the wheels i thought i may have made a mistake with my backspacing,then after doing some reading if I'm not wrong these should work but there sticking out about 2.5 inches out my wheel well.So after doing some figuring I got to thinking about something,the bearing on the axles is setting back towards the splines about 1in from the axle flange it self,the axles are 31-spline mosers that were in the rearend when i bought it,also it has disk brakes and the rotor hat sticks out about 1.5 or so if I'm remember correctly.Sorry for the long post guy's just needing some input.THANKS!
