Unless you have adjusters and they have been adjusted up I don't know what would make it sit higher than normal?
When you remove the metal body and replace it with a shortened fiberglass body, the suspension naturally raises up a little due to the decreased weight . . . but in letsbuggy's case, that's the thickest fiberglass body I've ever seen! I wouldn't be surprised if it's as heavy as a Beetle, so maybe it does have adjusters installed to raise it up. If so, adjust them back down.
If you are going off road, the extra lift is desirable (it gives you more cushion when you land on the other side of the dune!) but for a strickly street driven buggy, dropping back down might improve handling.
The "easy" way to lower a torsion beam suspension is to remove some of the leaves from the torsion springs . . . lots of folks have lowered there front beam that way over the years, but it's not recommended. It could be dangerous!
The best way would be to install adjusters on the front beam, or buy a front beam with the adjusters already installed and swap the parts from your current beam. Dropped spindles are another option, and they are usually the best option for lowering a bug because they don't mess with the geometery of the front suspension. But my personal opinion is since you are trying to get back to "normal" ride hight, the adjustable beam would be best. If you do the swap yourself, you should be able to buy and install a lowered beam for well under $200.
