@1967 GT+S in Whittier Ca

I grew up in Montebello and was a regular on Whittier Blvd and Bob's Big Boy on Friday and Saturday nights starting in the later '60s. After getting married, I lived on Beverly Blvd. (remember all the big pine trees) from 1970-72, then moved to Orange County where I still live.
There's still an active "cruise night" at the Ruby's restaurant at the old Whitwood mall on Whittier Blvd. on Friday nights.
Gotta say I haven't seen the Dart you describe at Ruby's any time I've been there but will keep my eyes open for it.

BTW, in case you didn't know, the timing tower (from the drag strip at the old Ontario Speedway) in your avatar pic is now a security tower for the parking lot just inside Gate 17 for the drag strip at the Fairplex in Pomona. Look for it if you ever get up to either the WinterNationals or Finals.
