Correct headlamp shell for 1972 roadster

I am looking for a new Headlamp shell for my 72 and was kind of confused with the new production Lucas shells

they are available with single grommet hole or with three grommet holes in the back under part number 54526651
which looks correct for the commando , any one know which is correct single or three grommets ?

If you take a look at your Commando's wiring, then hopefully, if standard, you should find that only the headlamp section of the wiring harness goes into the shell, so it's the single grommet shell.

Thanks Lab

i will get the single hole shell ordered this week
