Couplers Climax - Recomendations How to Change to Hook and Loop

[wagnera361]

Hello All, Does anyone have experience with or recommendations on availability and method of changing Climax truck mounted knuckle to truck mounted hook and loop. The coupler shaft screwed to the face of the truck does not seem to fit the channel in LGB couplers. The Bachmann spare parts store shows hook and loop couplers that look identical to LGB. Any help would be appreciated.
