Hey John. I wasn't able to find anything with those part numbers. What are trying to do with this information and what year, make, and model is your 5th wheel trailer?

You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

@JohnC Thanks for the information! If by hitch extension you mean a new pin box, there should be a white sticker on your current pin box, or above it, that says date of manufacture, possibly weight capacity, and have some form of RPO, LCI, or serial number on it. If you could email me a picture of it or carefully put all that information where it says Reply, I can find your bolt pattern and give you some options for replacement pin boxes. If you're emailing me a picture go ahead and send it directly to the address you receive this response from.
