Rudder Trolley Dimensions?

[Marvin]

Hey guys,

I apologized if this is already on this forum but I couldn't seem to find it?

I am looking for the length of the trolley that the rudders move fore and aft for adjustment?  Doesn't have to be precise, but just general overall length of the trolley bars (for lack of better word)?

I am designing a trolley type system so my Slawdevice rudders can be adjusted fore and aft.  Just need to figure out how long those bars are.

Thanks in advance!
