Well, it was definently a rookie mistake, should of taken the time to feel out the boat more......Called Grady, they told me about the access holes behind the back cushions on the port and starboard benches.
Had Wednesday off from my training schedule, so I used that time to get them on, pulled the bolsters off, found 3 access holes (factory used to mount the hardtop) and yes they are all only 1" fender washers even on the hardtop from factory.
I did my best to used thier sketch (emailed from Grady that morning) with the measurements + the #s Bill posted on the forum to find a food symetrical fit.
After alot of pencil marks and holding in place at various angles, I settled on a spot and went for it, got both sides mounted in about 4hrs. Im afraid I mounted them with too much of an aft-leading angle though, Lee's says 30degrees, but after comparing the pics of other installs vs mine, it appears mine are at a steaper angle.
Mounts I bought used, poles were new.....after all that work I was really looking forward to mounting poles and have it ready for action, opened up the box and sure enough the shipped the wrong ones (1-1/2' vs 1-3/4" as a I ordered)....so now Im in waiting for new poles and I have to go to the trouble to ship back to dealer (reembursed, but stll PIA)
Hope it all works out, it was tuff and scary guessing, but I think it will work out nicely......still TBD.
