Do you know which type your after as there where a couple fitted in 1970,
all look simular just the relays are different really, some have a big headlamp relay, some have a standard size relay,
part numbers also differ
411 937 505A- Big relay
411 937 505B- Standard size..(harder to find)
these boxes where also fitted to type 4's
i have a spare big relay type.. from a '70
