just went through this! Both bolt in identically & fit mechanically. BUT: UK has banjo fittings on cylinder & it has different linkage actuating bar. To use a UK cylinder you'd have to refabricate the fittings & fabricate the small actuating rod as its cylinder end uses a smaller pin & this cannot have any slop or play in them. I bought a new UK version to find all this out. Could not find a new USA version for sale anywhere so I had my old cylinder rebuilt by a hydraulic shop because my style cylinder did not closely match the MF parts schematic & I could not see how the upper part came apart. It was suppose to have a snap ring under the dirt seal but when I remove the seal: no snap ring! I asked the guy at the shop how they were going to take it apart & he dug around with a sharp pick & showed me that instead of a snap ring they used a flat spiral washer that you peeled out. Never seen or heard of one before.
PS: I broke the ear on the UK actuating piston trying to press a drift pin through it. The US version used a 3/16 pin but the UK is smaller. I initially tried drilling out the ears to 3/16 but it was so tempered that it ruined my cobalt bit & then my cobalt mill. So I welded the 3/16 hole in the rod shut & drilled it to same size as the Uk ear. None of my metric supplies fit it, so that's when I tried the collapsible drift pin. It would cost $150 to replace what I broke so that's when I opted to just rebuild the old unit. What an ordeal.
