The 93 Park Avenue Ultra has the same exact PCM, should have the Same Mem-Cal, and same trans as the Bonneville, no diffrent... But its a tad larger being a C body as opposed to an H-Body.... But the Drivetrain is the same
There is a Burgundy over silver Ultra on my way to work, man O man is that thing Mint.... Wish they would put a for sale sign on it...
