looking for a pair of tie bar saddles for bravo drives pm me if u got thanks

I have a tie/center bar and wing-plate saddles w/clevis joints.I will try and PM you some photos.

I have one new saddle someplace. $50. plus the ride. If you want it I'll dig for it after the holiday,

whats the theory with running two tie bars? i have seen many boats set up this way. curious what the benefits are and if they tend to bind or work against eachother. any info would be appreciated, thanks
