      Backspacing Help ASAP

      I have a 70 Chevelle I'm gonna run 18 X 8 1/2 in the front and 18 X 10 in the rear. The car is stock with lowering springs need to know back spacing and best tire size to use as soon as possible. Also, it has a 10 bolt in it now if I swap to a 12 bolt later on will it be the same.

      Ended up ordering them got 18.5 with a 4.5 backspace and 20x10 with a 5.25 (didnt have 5.5). I am hoping that the rears will work.
      For tire sizes i got 245-40-18 and 275-40-20
