How is that site Hoser? I have never used them, are the parts discontinued and they don't allow a purchase?

Have no clue on the threads you will have to order one and try these are the ones I would be ordering if I needed the nut to try.

Never had a problem with this site

ALL sites or shops will ALWAYS have the problem of selling you parts that are "available" then telling you later on "oops that part is no longer available" NONE of the shops are able to get and maintain real time inventory status on parts, you would think with todays computerized systems they could simply verify each part before they place the order and charge you then reserve that part at the same time.

Apparently were still in the stone ages when it comes to logistics.
