Weaver Davit question
I have a 8.5 ft zodiac. it has the weaver parts on the zodiac and the holes drilled on the swim grid and the u bolts for the stand offs on the transom. my question is where is the cheapest place to get parts and how do i know what i need. I look at the head pieces and there are drops 4 or 6 in extension. I don't want to drill any new holes just put back what was there. how do i know how long of stand off's to use.
