QA Adapter for 300 series to 500 series

[justwannafarm]

Does anyone know if an adapter exists to take a 300 series attachment and use it on a 500 series loader? I have one attachment that doesn't have the two sets of pins on it and as luck would have it the pin is for the 300 series. I was thinking of sacrificing a bale spear and welding the one carrier to the other however and adapter might be nice in case I find any more attachments that don't have the dual pins.



Thanks
Mike
