Lhm
Yep, you got the LHM correct.
All Khamsins, Boras, Meraks and late Indys had some items that ran off this system. Good system when in fine fettle, but as with all things if left, age kicks in and you get a load of leaks as it runs at 2500 psi.
The early Meraks had brakes, headlights and maybe clutch that were LHM controlled. Can't remember if anything else was run off the system. Later SS versions dropped the LHM system and therefore are less complex and more traditional in terms of engineering.
Late Indy's had LHM brakes
Khamsins have the Steering, brakes, clutch, seat, headlights all running off the LHM.
Boras had LHM brakes, pedal box, headlights. Not sure if clutch was LHM.
All items for the system can be rebuilt so shouldn't frighten anyone off (I've had some fun on my Khamsin that's still on going). I think with the Merak's (as with all 70's Italian cars) it's the rust that needs to be watched for, as I think that can be the biggest cost unless you are of know an ace metal worker.
Oh the Euro spares pictures of the Top Gear wreck are old as I don't think it's in that state anymore. But if at the time an engine could have been found I think the body looked good.
