Robert,
If you haven't already done so, go to Mike Dailey's Pantera Place and download a copy of all the electrical diagrams. There is one for the starter override circuit and as Paul says it is part of the seat belt and parking brake circuit. Most cars I know don't have any of that remaining.

I assume the Aldan's are true Aldans with a std 2.5" dia. spring and not the ones Hall sold with 4.5" dia.? Spring length should be 10" or 12" and easily measured once removed. Sourcing a spring the correct length and required rating shoudl not be difficult.
If the shocks are the Hall ones, then you can convert them to std 2.5" dia. springs, but will require new locators/perches.
