All right, Rice701 and I have been at eachother's throats this evening on the subject of frame tie-ins for cages. We need some input from those who are in the know.
My position is that a triangular, boxed, gussetted mount (just like the stock body mount plates) with a poly bushing on top of it (again, like stock with a boat roller, hockey puck, etc) through bolted and washered with beefy Grade 8 hardware is the way to go. This allows for strength, some torsional flex (with the frame), and isolates the cage from some vibration.
Rice's position is that the poly busing won't take the stress and will fold in critical situations. Instead he proposes that PBM's design with NO bushing and minimal shock absorbtion is superior:
Now I'm not knocking PBM's design, because I know it was purpose built for relieving stress on a fiberglass frame, it was easy to fab for the given space, and let's face it, the man has BEEN there first hand. But it would seem to me that under stress from off-angle this would fold faster than the stock body-mount design.
So let's get the guru's to weigh-in on this one. What's the best way to tie in the feet of a full cage to the frame?
