9inch question

Can anyone help me? I have a 93 notch with a moser 9inch in it I bought the car this way. Anyways I was told a 15x10 6 1/2 backspace with a 28x10.5 will fit my car. Right now Im running a 27560R15 micky drag radial with a 15x 8 and 4 1/2 backspace which leaves me a 1.625 of an inch at its tightest point on the inside of the inner fender. I was told I would have to beat the inside alot to make it fit but Im worried the privous owner might have ordered a wider rearend so my question is whats the stock width on a 93 notch with a 8.8 or 9inch and where r u measureing from so I can see if I have stock width rearend or not....:confused

I think you measure from drum face to drum face
