older la 351 valve parts

[nfisheremti]

does anyone have any ideas where to get the spring retaining screw on the float detent side for an older la-351 control valve? mine has gotten too worn and will no longer go into float. i pulled the valve apart, and the thing looks pretty worn and dented. any idea who might carry them. kubota, no longer sells kits because it is too old. the tractor is a 1996 b2400 hst. the new one has a completely different float detent setup

thanks for any help you can give me.
