1993; not all equal
Not sure if this is common knowledge, but the 93 flunked the fat farm test and reclassified the ZR-1 under EPA guidelines....in order to cut 3.8kgs and get back into their class, GM reduced tank size to 18.5 Gallons vs 20, changed fuel necks, losing a steel frame extension in excahnge of aluminum foam filler instead of honeycomb in the bumper.
Apparently there are 160 fatty 93 Zs with 20G tanks, and the rest skinnied up....
