reply: this is the closest I could find in a quick search. As time is money, I can't spend all day looking. Likely the measurements are metric as 7 1/8 x 2 3/4 is converted to 180.975mm x 69.85mm. We would say it is a 180 x 70mm pin. this is because most manufacturer's (even "American Companies") don't produce equipment in the USA. Caterpillar for example has 110 factories world wide. As you will see in this link the seller claims 6.5 inches usable. If you were to remove the thickness of the plate and the taper on the end, I would assume that is about what you would have, but I didn't measure it so that is purely conjecture. Hope this helps.

Reason:
thank you for the opinion, but the side of the one in the reference link is 5-5/8" or 143 mm USEABLE LENGTH & Diameter is APPROX 2-5/16 , more like 60MM which is not the size of the one in my listing, thank you

This is called a Bucket Pin. Judging by the elongated slot it is a replacement pin not designed for any particular make or model, so in reality it could fit hundreds of applications. I would suggest to get a ball park price by searching for Bucket pins the same size in both SAE and metric sizes and list it accordingly. The other thing buyer's will need is the distance from the center of the pin to the retaining slot, and the width of the slot. Rockwell hardness would also be good, but not necessary. Good luck

Reason:
Hey, is there any way you can find one with the same measurements? The person who answered before you linked the right kind, but the wrong size. I can accept the opinion if a link to a matching size can be provided.
