Nickey Sold Nova- Researching History

[Pro Stock John]

I'm helping a friend research a car he owns, here are details:

1969 Nova SS
L34
4 speed manual
black/black
Purchased from Nickey new
Supposedly car had been in Chicago area up until around 2018

Day 2 modifications include:
LS6, some work by Skip's Performance in Mt. Prospect
Tunnel ram, dual 660s
TH400
12 bolt, 4.56 gears, has early TA cover
Flares
Slotted wheels, Fentons and Gyros
Appliance headers

Car was sold out of the area by John Platania. A longtime past owner reportedly worked for Flying Tigers Airways as a mechanic and lived in Desplaines. Through research have heard there was a guy named Don Clemons who might have been that guy.

Welcome any clues, hints, info. Have already tagged Stefano on FB with a post and hit up some of the local FB groups.
