Chevy rotors on 73-76 A Body spindles

Not sure if this can be done and not sure where I really need to ask this question so I’ll start here. I have Race Star Dark Star wheels on the rear of my 64 Valiant, 8 3/4. I have been looking for a front wheels to match, 15x5. Sadly they don’t make them anymore in 4.5 bolt pattern but I did find many with 4.75 Chevy. I converted the front brakes to 73-76 disc’s already. So my question is, is there Chevy rotors I can buy that will fit the 73-76 spindles so I can get the wheels I want? Thanks
