i sold one last year for $500,there are people out there for them although a limited audience

 

The gear ratio will be important as well. The police-only 3.42 will be worth a lot, although it appears that by 1968 that was no longer offered. 2.56 and 2.73 were the most common ratios. 3.08 was optional. There was also a 3.23 ratio but again by 68 it was no longer available.
