Is there an after market reel clamp for my 870-2 speed that fits over the reel seat, because I dont want to only rely on the factory clamp, Thanks.

Chark has several types-take the reel and perhaps the rod for the best fit

I was looking for some kind of clamp that could go over and use the real seat because I hate to rely on those two 10/32 bolts. I saw a shimano clamp for the trinadad like what I am talking about.
