be careful... dialing in 30 or up 45 on the loos guage with a wrench will almost certainly gall the threads..

Usually you flip the boat... pull a diamond off the spreader.... dial in the threads you want... bow string the diamond back on and off you go... can be done on the water as well... but a PIA...

The a cats build a lever arm with an internal three to one purchase to dial in tension.... the two turn buckles set your low setting and straighten the stick for wire variablity...

That piece might be different... but I would be care full.
