Police Pursuit Diplomat 360 turbo ???
Had a 1978 LeBaron 318 4 door.
Back in 1991 I did a lot of mods to that car using some Police Dippy parts and Firm Feel parts. With lots of welding and axing the rubber body mounts it rode a bit stiffer but would corner very well. Bilstein shocks were well worth it.
A 360 with 375 HP, A999 with low gear, 8 1/4 (2.91:1) with a set of 3.55:1 8 3/8 truck Suregrip, no rubber axel mount and a forward shock as a traction device.
It was a Grandma's sleeper.
