Winch bolt patterns

We have a Barient 18 and an Andersen 18st on our deck house - I would like to swap the positions of the winches. I REALLY do not want to drill holes! Does anyone know if the bolt patterns are the same?

thanks!

Unzip the headliner and take a look.

great idea! (not sure why I didn't think of that...)

Don't know about the Anderson, but the Barient 18 has 5 holes on a 3.375" bolt circle, spaced 60-degrees apart.

My theory is that if they have the same number of bolts, they will be similarly situated angularly but the bases will be different enough that the holes will not quite line up.

This theory is grounded in years of observing empirical evidence of entropy: bolt holes simply never line up. Grin and fill and (re-)drill it.
