probably not in stock, but in the US, should be able to get it within 2 weeks. If you tractor isn't in stock and is being assembled and delivered, they can probably have it done by the time you get it. I had them install that, and weld on some chain and clevis hooks before it was delivered to me. These days, I'd probably go with bolt on hooks vs weld on, the quality of the welds don't impress me.
If were to do it again, I might go with something like this with a removable shackle. If you have a built in D ring, it's going to be banging around all the time.
