275/60/15 sidewall clearance to leaf spring clamps- suggestions?

I just happened to be searching spacers and came across this thread. I have a similar situation but I'm running an 8.75 that was originally a B body rearend. I had it narrowed but in my haste didn't account for the 11 inch breaks. I made the adjustment with my aftermarket Rallye's using a 4" backspace. I have 1/8" clearance on my springs using 275's but for some reason the clearance on the right side at the front of the spring is only a sliver so I'm looking for a minimal spacer. The issue there is (as someone already mentioned) the outside gets closer to the wheel well lip. It should be fine but could be an issue if you hit a good dip in the road. This brings me to another point, primarily for you, #RustyRatRod... Is that your Duster (PRETTY)? If so, How did you attain that ride height in the Rear. I dumped my air shocks and even though these cars tend to set a little low in the rear, mine seems to sag more than it should, especially considering the rear tires are over an inch taller than the fronts. Looking for options besides air shocks again. Have new Monroes on there now.
