Although Thor CSR was extremely helpful they would not send me parts for window screen latch, they refereed me to a dealer.
I have the part numbers-
Twist and lock #s are 0370435 & 0370455 (these are on bottom corners of mine)
Stationary # is 0375758 (these are on top corners of mine)
Hope this helps in some small way, I yet to get a cost on these things from a dealer.
