Hey everyone, sorry if this topic has been beaten to death already but I have a rim/backspacing questions. I don't want to screw this up lol.

I'm planning on running 18" wheels on my 69 fleet with a 3.5/5 drop. 99% sure I have the narrower rear end, but I will measure again to make sure. From face of drums I was a little over 62". So my question is what would be ideal backspacing on a 18 x 8 up front and 18 x 9 or 18 x 9.5 in the rear? Thanks in advance.
