Any Girliing 0.7 master cylinder or 0.7 re-man Girling copy should fit.

You just need to use your old push rod.

You could use a seal kit and make a big saving but they don't always take.

If you do kit the cylinder its best practice to carefully hone the bore of your old cylinder before fitting the new seals to remove any score marks or ridges.

cheers for the info, my cylinder has started to weep probably due to being unused for 2 years before i bought it. i bought one off ebay from Triumph-Recycler for £26 delivered with an adapter just incase i needed it

Very nice gadget but even the smaller version only goes down to 20mm dia. that ain't gonna fit a 0.7" bore cylinder!

For the modest price of a new cylinder I personally wouldn't even consider messing about with seal kits. do it once and do it right

I re-read 2 0r 3 times...are you talking about the brass pipe fitting on the master cylinder? as this is a 1/2 inch spanner.
