11" Backing Plate Differences

Thank You for that bit of info, thats exactly what I was looking for. The spacer under the drum doesn't bother me so much, It allows the 2.5 shoe/drum to work with the 2" backing plate, except the wheels I'm interested in have about .5" different offset, pushing the outside of the wheel/tire closer to the quarter, where I'm already pretty close. It only buys me 1/4" per side though because thats about what those spacers are, and makes perfect sense after reading- "If you get ~1.75", you have 11x2.5" plates. If you get ~1.5", you have 11x2" plates."

Maybe I'll just stay with the wheels I've been using until I decide if I'm going to utilize a modded Exploder 8.8 which is about an inch narrower than my current rear with said spacers. And that would get me my 1/2" needed per side.
