Yes. Both machines were built with this engine, and the serial prefix and build code from the plate are what the order is matched against.
Two builds sit inside the 5XK range and they do not share pistons: one record ties 107-0984 to the engine and a second ties 128-3295 to it, so the serial decides.
Rebuild kits and oil pumps carry both names on one line, with 32B35-00011 and 32B35-20010 listed for Mitsubishi under S6S. The S6S family covers a wide output range, so the build is still fixed before dispatch.
All three conditions are traded and the condition is written into the quotation.
No, it is a 4.0 litre unit of 100 mm by 127 mm bore and stroke.
