I ran across this on a different forum I am on. Perhaps it could be helpful to you?

And, just keep in mind, one of the factory aimers are right in the center of the pre-98 lamp. Its possible to have your highbeam socket where the stock piece is, but it might make you run a really small lamp. Of course, that is only if you plan on using the OEM aimers. If you use a different lamp, like the 90mm units from Hella, they have thier own aimers and it could make your job slightly easier.
Something tells me that your are somewhat going after the look that is on my car.
