Hydrolastic: Classic MK1 vs Innocenti

[rogerotto66s]

I own a 1966 “S” and may have the opportunity to obtain “wet” parts from an Innocenti. The parts would include radius arms, displacers and possibly subframes.

Are all these Innocenti hydro parts compatible with Classic MK1 minis?

Can anyone provide info?
Thanks in advance.

Disclaimer: I am by no means an expert in Hydrolastics, but do have some clue about Innocentis.
So rather than not getting any answer I thought I share my semi-professional best guess with you.

The radius arms, the subframes and all the other Hydrolastic bobbins of the Innocentis should be 1:1 compatible to you british Mk1. The displacers may have a different rate (think there was info on the colour marking of displacers somewhere else here recently). The subframes, of 70s Innocentis at least, were built by firsat rather than Mowog. But that doesn't necessarily apply to earlier Innocentis.
So I assume they can be used more or less as a like-for-like replacement.

The expert on Innocentis is Lorenzo Battaglia, his web page in Italian where you also find his contact details:

As far as I know Innocenti didn't start pressing their own panels until the early 70s so anything from before then should be 100% compatible

Thanks all for the great info.
