"LT" was also used as the logo, and name of the retail store I once owned.
"61".......I raced a #6 stock car in 1975, at the local paved oval, (street stock division). They already had a #6 car, so I HAD to change my car number, I picked...........#61.
In 1995, I resurected the #61 on my 1:10th scale electric R/C race (pan) car in Florida.
