Mike---I need one of 2 things to work with my hitch either

the round trunnion bars

OR

the hitch head the part the ball fastens to for a bolt together adjustable height hitch bar for FLAT bar trunnions

Make sense???

The insurance company replaced my hitch with an adjustable head hitch but it is for a round bar trunnion not a flat bar trunnion-- I only have flat bar trunnions but the hitch head I have for a flat bar set up is the welded/fixed ball mount NOT ADJUSTABLE need to raise the ball up about 2-3 inches cannot do it with my setup--- can u help me??
Thanx Dick Ullrich FED387
