Shocks:
If you have non-88 LCA's, any EF, DA or EG/DC rear shock will fit, but some are better than others. The DA shock, for instance, is about 1.5" longer than the stock EF shock. Just for the record, this height difference is ABOVE the perch. That means that your car will be the same height regardless of what shock you run. Travel is your friend and there is no sense in putting a longer shock in there unless you are going to raise it up and go rallying. The DA shocks, though, are valved stiffer than their EF counterpart.
