Window Tilt Latch

I attach a print from www.amscousa.com who do not supply outside US showing sizes plus a photo of my existing part from my Ducana window. I was looking at parts 26-078 and 26-079 in white which might be suitable and less expensive than 26-188W. I need 6 of each of the nylon parts if you think they are suitable. If you need further information, please let me know. Once I hear from you I will place an order to send to Scotland, UK. Thanks

Thank you, handy person from Aberdeen for putting up this picture. We (also in Scotland) were looking for the exact same thing and only found it thanks to you. Thank you Tom from Swisco for comforting us that we could buy the right part.
