So to be clear the pin on QA B1658 will fit on a LA 304 loader for a Kubota B2320.I might be able to look it up in the wholegoods PDF file I have. Need to start from the tractor though, so if I know what model tractor you have I can see if the loader is listed, and what options are available for it. I know the B1658 that BAP showed fits the LA3xx series ( I have it on my LA 304, and it fits the La 364, and also the LA 504,(the only loader Kubota listed it for on the B 2x20 serie tractors), so it may also fit other loaders.
