Booster/Vacuum and boltin replacements?

[CMF_Alex_B]

Discovered today that my booster diaphragm has gone and a new anti-skid booster from nissan is $747AUD. Their is differences between the std and anti-skid boosters with diaphragm size (abs has bigger diaphragm) and pushrod length varies,

So this brings the question, has anyone any knowledge to share on the possible fitting of other boosters, N14/N15? and perhaps master cyclinders,

Alex - i've been quoted $250ish to rebuild mine
