I strongly recommend you find a copy of a book called 'Womens rights, A practical guide' by Anna Coote and Tess Gill, published in 1974. It will open your eyes to how much womens rights have changed since the late 60's.
Page 22 of this book notes for example that they expected the Equal Pay act to come into full force in 1975. (Which it did, just about, 29th December 1975).
Page 150 notes that at this time marital rape is extremely difficult to prove and is not illegal even if you had started divorce proceedings.
Page 260 notes that at this time some single women could get mortgages but that many providers would require a male signatory. Many married women found that mortgage providers didn't take their earnings into account when calculating borrowing amounts, only the husband's earnings were considered.
Honestly it is my favourite book if only to remind me how far we have come, and how much of a social change we have seen insuch a short time period (50 or so years). It is well worth a read if this is a serious area of research OP.
