I can’t say I’ve ever seen an auto pilot servo that looks like that one. I just looked in the parts book and it only shows one part number for the auto pilot unit for all C-bodies and Imperial so this is some sort of replacement?
Looks like mauve metallic. Nice car!
And air shocks are also a horrible idea if the intent is to increase the rear ride height as the rear shock crossmember was not engineered to actually support the weight of the vehicle. This is the leaf springs job not the shocks.
