Ok, I knew I wasnt insane. I cut myself some slack because I own and maintain seven mitsubishi's and hardly any two are the same.
When I put new axles in, i backed out of the garage and the ABS started working it's butt off the second i tried to stop my roll. I pulled back into the garage and inspected the car, at the time I'm not sure why it didnt occur to me that the ABS ring is on the wheel hub but the drivers side had an ABS ring, passenger did not. Obviously these axles are used in a number of vehicles, according to Rock Auto:
EAGLE 2000 GTX (1991 - 1992)
EAGLE SUMMIT (1992 - 1996)
EAGLE TALON (1990 - 1998)
MITSUBISHI ECLIPSE (1990 - 1999)
MITSUBISHI EXPO (1992 - 1995)
MITSUBISHI EXPO LRV 1993
MITSUBISHI GALANT (1990 - 1992)
PLYMOUTH COLT (1993 - 1994)
PLYMOUTH COLT VISTA 1992
PLYMOUTH LASER (1992 - 1994)
All of these vehicles use the same driverside axle, so if any one of them calls for an ABS ring, I likely ended up with that model's axle.
That being said, it doesnt explain why the ABS was acting up. I'll be looking into that the first chance I get.
Pics for proof;
And just because I got such a kick out of this service record from the original owner;
