awesome guys! THANK YOU for these posts. The science of wheel measurements has always been foggy. You describe it better than pictures. I don't have the rear end yet. I DO know its a '68. I'm wanting to run 15" steelies or torque thrust D's. I'll get to measuring once its all mounted up

How big of a tire do you want to run?

If you're going to run a B rear and move the perches, I'd get an offset hanger kit too. No need to do the full 3" relocation, but you might as well get the extra 1/2" to 3/4" since you're moving the perches already.

15" steelies might be hard to get the most out of unless you go custom, I don't think they have anything in the 6" backspace range. Torque thrusts would be easier to get in that kind of offset. And if you go with offset hangers, you can add some more backspace as well.
