Thanks for your photos. Can you confirm the length of the metal channel? Based on your stamp of 4230, it should be 43" long, not 42". Either way this will have to be a custom order due to its extra large length. 

I'd also like you to refer to the diagram below and tell me which measurement more accurately matches your own bottom nylon fitting. That will be a huge help.

Finally, how many did you need? 

Please confirm those details and we can get the ball rolling!
