Bazza, the car, has been reunited with Bazza, the man.

If he needs Dizzy cap and rotor I believe a rover v8 cap and rotor fit the later lucas electronic, so i'd be 80% on them fitting the points version as well. just been through this with a mate

I had the distributor professionally rebuilt by "THE" Lucas guy here in the States. Turns out his shop is about 20 minutes from the office, and while he's rebuilt "at least 20 thousand" 4 cylinder Lucas distributors (MG's, Land Rovers, etc), he had never gotten his hands on the V8 version (I forget the model). Apparently the points are Rolls Royce, and the cap....Damn! I've forgotten! (Land Rover?)

that aircon vaccuum water tap on the inner wing... i doubt you will find another but a tap from a US car might be mountable on the bracket.

The powerhead (vacuum canister) turned out to be good, and I did find a couple valves, but at Bazza's request I didn't make the repair(s), as this will be something simple he can do as he recuperates.

Thank you for all of your help on this, Dave!
