Looking for part numbers for a P-30 Chassis steering parts

[Evildodge]

I have been trying unsuccessfully to track down the following items for my 1987 Fleetwood Bounder, which rides on a P-30 Chassis.

Lower control arms
Inner and outer tie rods
Drag link

I sourced shocks and bell cranks from Super Steer but so far everything I have looked at from local auto parts stores has either produced no results, or wrong parts. Any help would be appreciated!
