Pella slider door handle

Hello, I am looking for a Pella slider door handle -(we just used rollers we ordered from you- part # 81-098) the center mounting screw holes are 6" 5/8 to 6" 3/4. (our customer bored holes to make larger and am not sure of true measurement) What we need looks like your part # 82-218 but is too small. the turning level to lock is off center in comparison to part # 82-218- (although it can be changed if needed to fit a new one) Thank you for your help!

I do not have any photos to provide to you so I hope this detailed inquiry will be enough for your team to recommend a part.
