I need a bow roller for my 2000 MFI trailer. The one I need is 3" diameter and 4" long. It also requires 2 x 3" diameter (I'll call them doughnuts), that go on the outside of both sides of the mounting bracket. It is really a 3 piece bow roller. Also need it in the Poly so that it won't marr the hull. Do yall know of any board sponsors that might could help me out? Thanks in advance for your replies.
