can anyone confirm that the stanchion bolt size is 1/4"-20. i took the stanchion and backing plates down to the marina today. forget to measure the bolt hole size before i came home and left the stanchion down there. so now i have no idea what to order this week for next weekend, ugh...
Yes,1/4-20 is the thread size on Shamrock. Length varied 1 3/4, 2 and some longer.
