You would need the same size shoes to match your b.plates.2 1/2 shoes,2 1/2 b.plates.Hope this helps!I,ve just done this on my 8 3/4 but with 2 1/2 by 10 and had to get matching b.plates.

Thanks for the info all, Im making a trip back to the yard I bought the back plates at, I think I remember seeing the old shoes under the car!
