I did the 'doughnut' thing on my 84.  I actually used some sheet aluminum
rather than plastic.  I added a peice, about 3/8" thick -- cut it to fit the
spring perch, but I did mine to even out the load at the rear wheels for
traction rather than for ride height.  Wasn't hard.  You can get aluminum
sheeting at the hardware stores and simply cut it with a saber saw to fit.
I used a spring compressor to make room for the shim...A cheap-o one from a
chain autoparts store, the spring compressor...
