Backspacing on rims

Question, what would be a good backspacing on the front and rear of a 1967 chevy truck.

Information:
-The truck has disk brakes all the way around.
-The measurements are 65" hub to hub in the front and 64" hub to hub in the rear.
-Will be installing 18"x7 or 8 Bonspeed Clutch rims.
-Installed a 2/4 drop

Tring to find a good backspacing that will put my tires just a bit inside the wheel well, and line up. I am trying to see if you guys have used a combo that works great.

Either a 4 or 4.5 inch backspace should work fine. I would stick with the 8 inch rims, due to better tire selection. You can also get a 9.5 inch wide rim on the back! Do you have any pics of the truck?

Here are a few pictures of what my truck use to look like before I tore it down. It’s roughly the same except for the changes I said previously. The tire combo that I had before the tear down were 15" x 8" Crager deep dish all the way around. These rims had 2.5" of backspacing and kind of stuck out in the front about 1/2", but due to changing all of the front suspension components to New this will change my geometry just a little (wont sag as bad).

Nice truck! Stick with a 4 to 4.5 inch backspace,... and a minimum of a 50 series tire to fill up the fender well. You might look at some of the trucks in the picture section to get ideas.

Thanks for the advice

After doing some measuring and putting some different combos (BS, widths & sizes) on paper. I think I need a 4.5" BS in the front and a 4" BS in the rear. This will set the tires at 72" rim tip to rim tip while on the truck; this should give me the desired "inside the wheel well" look I am after.
