My impression is that the 143.5 was just a quite amazing typo! I 
believe that the pushrod length is the same for both single and 
tandem MCs since people have switched without changing this distance.

My best guess is that the nominal average length should be 153.5mm.

Yeah, I'm gonna have to make up one of those templates one of these 
days. If only to see just how they are expected to work.
