OK this is what I have found from all the inquires I put in to Thor and other Thor dealers this is the only response I got.
I am in Texas but this RV dealer in Missouri is the only one who came through. They had a form where I gave the Vin# to be sure we got a match for the Thor part
So I have to suggest anyone needing or wanting a replacement lens to contact them and give them your Vin#
I ordered two as I never wish to have to go through this again.They have the clear lens or amber
Ron,
This is the Acorn lens, our # 236418 & 236419 both $5.99 plus shipping. Would you like clear or amber? I will then email an invoice, will call for a credit card number and we can ship it out for you.
