Fleetwood gearbox broken ramp door

After several trips to several service centers and fleetwood service centers I have found that the trailer owners have been abandoned by fleetwood and there is no source for parts and the part that shows shows no longer manufactured and supplier has no stock to manufacture part. All that is a long way to say we had to go to plan B. So we trimmed pin stubs back so they didn't interfere and welded 4 greasable bullet style hinges to the ramp and rear cross member. They cause the pivot of the door to occur about an inch further backwards but see to have no difficulty and assist springs from factory have no added tension because of this fact. I spoke to a couple of close trailer builders in the area and they all said these are the hinges and the number they are using for car hauler so I figured my toys and possible the jeep occasionally should not be a problem.. Thanks to all for the help offered.
