Both my dad and I have 1850’s and my dad went the way of what that JLBASSIN above did. I myself just found this pedistal. Not sure about the lever not working or not as listed above but I think that was an older model like the ones on the Cresliner Seats that are so hard to work. Anyway, I am 6′-2″ tall and in my old boat and in my dads we have 22-29″ pedistals. So that is the height you should look at.
Unless JLBASSIN, or someone else knows something different, I think I am going to go and try the springfield pedistal. The cost is about $15 more than pulling out and replacing bases and then picking up the $65 pedistals and seats. Horse a peice I believe.
JLBASSIN is this the pedistal that you were refering to when you mentioned the little black lever doesn’t work?
Let me know, if so, I am going to pull the bases out as well and put in the 1.77′ pedistals for the front and read decks.
