RB Engine in A bodies - Air Cleaner Clearance Issues

I have a 500 CI RB in my 1973 Duster with stock hood (no scoop). The engine has a Edelbrock Torker II manifold and Edelbrock 14 inch air cleaner. I have rubbing with the hood insulation (just enough to take the paint off the air cleaner). Does anyone make a slightly shorter air cleaner that won't be restrictive?
