James Tractor Spare Parts always declares to have the part you need. They are know as a "scam" on a Grasshopper forum I frequent. I'd be VERY cautious dealing with them. They show a tractor salvage yard which misleads folks.
You might ask them to send some specific pictures of the items. See if you receives picture of what you ask. Do not send any funds hoping you get what you think they have. From what I've seen I would only purchase from them if I was there and saw the item in person, have it on my trailer with a bill of sale, then pay.
