Anyone out there know where I might find the control valve for a load leveler system? It mounts under the rear of the vehicle. I believe they are common to both Olds and Cadillac and may be similar for years other than 1966. I have the vacuum pump but it needs rebuilding. Any help with that would also be appreciated. Thanks, Bruce

 

Best I can do is the part #.

Grp 7.475, 66-67 except Toronado or Vista Cruiser, p/n 3188808, Valve assy, superlift shock absorber height control (automatic fill)

Listed for $46.05 in 1974. Expensive piece!
