27' fountain trim cables
 

I got a 27' fountain center console a while back to flip and it needs new trim tab cables. The previous owner cut the cables when he removed the console to redo the stringers. Does anyone have any idea of what the correct length cables should be? I can measure from the transom to where I think they will need to go for the console and probably get a good idea (16') but I was hoping someone might have done this and know the exact right ones to get.
Thanks for any input.

Pretty sure the cables are marked on both ends, so check the transom end if their still in place

That's the problem both ends were cut off and there is no writing anywhere on the cables themselves. The cables were actually rusted into the through hole on the tab so all that had to be drilled out.
