looking for kubota rims

[grandv8]

I am looking for a set of ag Kubota rims for a Kubota b7100, 4 lug fronts looking for 12" I believe. I have the 10" turf rims now but need the ag fronts so if any has some they are willing to trade sell etc or any links as to were I can buy them I would be much obliged.....

oh and what is the bolt pattern so if not readily available I may find a suitable replacement. I measured and from center to center it seems 2.75" but I want to be exact to order the right wheel. Thanks gents
