The two stationary landmarks (LOS) from Z-pedestal are the light signal post on the Houston St. corner and the parking sign further west down Houston St.
At Z166, JFK within the limo aligns with the Houston St corner light signal post.
The flashing part of the gif shows the ' + " sign designating Station# 3+25.0 and gives you an idea of the distance to JFK within the limo.
JFK's location at extant Z156 = Station# 3+19.3
JFK's location at extant Z166 = Station# 3+30.1
10 frames @ 10.8ft = 1.08ft per frame
1.08ft x 5 frames = 5.4ft horizontal = .295(3.54vertical inches) x 18.3 = 5.4ft horizontal
Extant Z161-Z166 = 5 frames
