Hi there
Many thanks for the pictures - I noticed the air vents on the sides of the doors (these were used on the later series vehicles - from memory)
Ae you going to keep the holden engine - or convert it back to Land rover.......either way its a tidy looking rig.
It also must have been a common after market conversion of the time - my Series One Fire Engine also has a remote brake booster fitted in the same place.
All the best
Wayne
