[Healeys] Brake backing plate bolts

[Michael Salter]

Yep Richard according to the parts books that's correct for 6 cylinder

As a matter of interest the late BN1's and BN2's ( 5 stud hub) use 8 plain
nuts but call for only 4 spring washers?? Weird ... I'll have to look into
that one ... there has to be a good reason.
