Sounds like using an 80 amp alternator with a max demand load of 60 amps with a good battery should work with the Lucas amp gauge-just pushing it to the limits for those peak demands when the battery is dead and everything is on.
Tough decision for originality.

I don't use amp meters on my cars, so I can say anything about using amp meters......I just prefer a volt gauge......My "amp meter" is to turn on the headlights and see how bright they are then, rev it to 2,000rpms and see if they get brighter....
An 60 to 80 amp alternator should work fine and as long as your battery is good condition, you shouldn't have any problems....My battery is a 7 year old, yes 7 year old Optima and it'll spin my motor over all I need and then some.........
One thing I've always done and may have contributed to the Optima's long life is when I know I will not be using my car for 2 weeks or more (which is sometimes often) I disconnect the positive battery terminal........
You may want to go to a local alternator shop and run your thoughts by them, they're experts in the field...
