replacement sliding door handle

A handy person from Kalamazoo, MI says:
I am looking for replacement handles for sliding patio glass doors. They are marked DOrWAL on the outer piece and
stamped 120 on the inner handle bracket and 103 on the handle itself. The screw holes are spaced 3 1/2 " apart.

I have tried numerous supposedly "universal" replacement handles which have proved too flimsy for this heavy 8 foot door. (This house was built in the late 1960's and there are 5 of these original doors.) The latest try has screws which are either too long (2")or too short (1 1/2") and too narrow for the holes in the door so that even when cinched up tight there is play when you move the door. We don't care so much about the cosmetics of the handles as getting something that truly fits and will not easily break.

We would appreciate any help you can give.

Good morning, and thanks for posting! Please take a look at our 82-055 Acorn Sliding Door Handle. Could you use this as a replacement? Let me know what you think.
