Sure, we may be able to help. Can you tell me the distance between the screw holes, center to center? Can you also show me how your handle latches? Thanks!
Thank you for the additional information. You might want to look at our 84-233. I believe this is used by "Carefree" manufacturing. However, the backset on the latch could be a different backset than yours, and we only carry this one size.
Measuring the metal inside latch, it is 1-7/8". That is from the end of the flat metal piece that goes into the handle to the end of the piece that latches onto your keeper. What is that dimensions for your own hardware?
The handle dimension is 3-1/2", which is the same as yours, at least.
