Best parts sources for the Delco Powermaster ABS systems?

[Centurion]

Hi all,

I'm new here, but I've been part of the Buick collector community for many years. I was advised that you folks might be able to provide input for me.

I've purchased a beautiful, low mileage 1990 Buick LeSabre coupe with the Delco Powermaster III integral ABS system. The car sat for a couple of years, and the pump in the system is inoperable. I need to replace the pump, or perhaps the entire pump/master cylinder/electronic controls unit.

I know that the TurboBuicks utilized a different version of the system, but thought you guys might be able to recommend reliable sources for new or remanufactured Powermaster ABS parts. Any input for me?

Are there people who remanufacture these systems?

Thanks in advance for any input you can provide.

I've read Orlando87 GN's post about replacing the Powermasters with a regular power brake system.

I've heard that this conversion gets real expensive because all brake lines must be replaced. Is this accurate?
