master cyl change ideas please

[aroma]

looking at changing my factory master cyl to a vac assisted one mounted on the firewall not bolted to the chassis
current one has plunger of 1- 1/8 dia by 1-1/2 inch travel ,one outlet going to drums all round
what would fit ,40 series crusier or ?????
would need the master cyl and pedal ,etc
would I need to cert this change ??
cheers

just stick a later model vac 40 series one in, they are twin outlet so you'd need to do a wee bit of plumbing

wernt they disc on the front? and could I plug one outlet, two outlets let would be a little too much plumbing as replace pipes while rebuilding it
