71 Low Rider
Trying to see what i can do to raise the back end an inch or two. Exhaust is up as high as it will go, correct tire pressure, new stock shocks Has original springs. Have the short main leaf spring bolts. Maybe put in one of those new mono leaf springs? Any ideas?
I keep scraping more times than i want to and am very careful going in and out of low areas and still scrape.

You must be one of the only guys trying to RAISE a C3 rather than lower it 
Roughly speaking are your 1/2 shafts sitting close to level or are they running lower towards the center?
You should have some thread adjustment on the spring to trailing arm bolts, if you run the nuts on farther it raises the rear, roughly 1:1 (not quite) or you could try 5" bolts rather than the stock 6" bolts if there's no thread to use.
If you want to look at the mono-leaf springs, most people complain that the TRW style ones (flared out at the ends so it's easy to identify them compared to the others that are basically square) sit too high even with 8" bolts so maybe that's an option

If all that stuff is new. You shouldn't be dragging on the ground. Measure from the floor to the inside upper edge of the wheel well. around 28 - 29 inches?
