Original part from Odyssey Group for RV Patio Sliding Door

Odyssey Group the supplier of these handles apparently went out of business quite some time ago. I was able to find reference to the original part including the supplier part number(s) OP57452 and OP57390/91. None of the RV manufacturers I've contacted have any available and no one has any information on a direct replacement. I don't have the actual old handle assembly so am unable to go off measurements. Have had a few people looking for this part recently. Am looking for a direct fit replacement part. If anyone reading this has one of these, the measurements would be really helpful.
