This is a drawing of my TR3A's bulkhead I made while I was rebuilding my TR3A. This is a left hand drive post TS-6000 bulkhead. #15B is a connection for an earlier pre-TS60000 TR. #22 may be an extra hole from a dreaded previous owner (DPO). I have never found it listed anywhere.

Bolt for mounting flasher unit. Early TR3As had a flasher with mounting tab at top. Late TR3As used a clamp strap over a standard flasher unit.

Commission plate has two mounting holes for pop rivets. Additionally there may be a second pair of holes if the car was provided with a year plate. A year plate in normally orange and has "STC - XY" where STC stands for Standard Triumph Company and XY are the last two digits of the year. These year plates converted a unsold, unused Triumph into the next model year.
