In Texas only 1 mirror is required either door or inside is ok. 2 Tail lights/stop lights/turn signals are required for 1960 and newer. Tail lights/stop lights have to work if mounted reguardless of year, turn signals do not have to work pre 60. SEATBELTS are not required if pre 60 or not a factory option. However if ANYBODY has ever installed them and made mounts for them they are now required to stay reguardless of year.
I was a Texas State vehicle inspector for 10 years and this came out of my DOT book at the time.
