for anyone else who wondered, I got the 411 on the Inno.  All brake stuff is SAE , not metric nuts or threads.  Order from any mini supplier with no fear it won't fit.

I don't have a good enough memory to be able to say with any strong conviction that the inno did or did not use metric brake hardware. My comment above referred only to the powerunit hardware (nuts and bolts in the engine and transmission).

The only mini variant I've ever personally experienced that I can say with any certainty that used metric brake fittings was an MG Metro. Well, the UK MK4 and MK5 minis use a metric brake master and had a conversion fitting mounted prior to the front subframe connection.

what about the brake lines and brake hoses?    Can the mini hoses be used front and rear on an Inno?  I have experienced the nuts on the hard lines as metric on an Innocenti. Would the threads also be metric? 

I've never found any hardware on the power units that were metric. The seals are the same as on all the other ones. Just confirm if it is hardyspicer or pot joint/yoke before you order.

Any Innocenti owners here.  A friend has a 1300 export and I've suggested a Haynes manual for him.   Are there any Inno manuals in English?

He's needing to replace the diff output seals.  Are they the same as the mini?  I'm wondering because of all the metric threads nuts and bolts if they require a special sized metric seal.
