1966-67 riveria

My father just passed away and had three riv's, 1-66 and 2-67. What is the market like for these and where can I locate the VIN to verify the title (can't make out if there is a number on the dash). Any help would be greatly appreciated.

There should be a vin # drivers side dash near windshield on the '67.... are you lookin to rid yourself of them? Sorry about your dad i lost my dad about 10 years ago.

Hello,Sorry about the loss of your father.I think some of older GMs had a plate on the firewall,That had the VIN# on it.The location would be on the left(drivers side),Or some had the plate on the right.As far as value of the cars would be,I would look around on the internet for car collector sites.Have a good day..Diesel 1962
