Guardian Patio Door Roller Replacement

A handy person from Canandaigua, NY says:
I have a Guardian patio door model:

8000 933 1/8U

16 OFR 1201 II
CAN OG8B/12.1-M

I'm looking for a replacement for the screen door roller assembly. I have measured and all the dimensions match your product code 84-138 EXCEPT for the screw hole measurement. My screw holes are 2 inches apart as opposed to 1-7/8" on your part. Is there are part in your catalog that matches my description?
