Did mine a couple of months ago. Are you doing it yourself? See if you can purchase or borrow a pneumatic impact wrench, because without it you could do damage. Need healthy hands for fishing. See if you can get the bolts for the shackles etc. with zirk fittings as they will extend their life. Did mine with boat on the trailer using a pneumatic hydraulic jack found on sale. All is quite simple just getting the nuts of the bolts took a little hammering. Sprayed all with liquid galvanize before install. Good luck!
