Default Swift Shift activation rod length problem with Suntour Power ratchets

Well, got my McMaster Carr 3/8" IS/5/8" OS washers and they fit like
magic in my ratchet shifters. But now it won't hold steady.

The support rod that connects with the power ratchets are 1mm longer
round base and 1mm longer oblong part for a combined difference of 2mm
total longer rod on Suntour down tube bracket (Right Silver) vs the
Swift Shift bracket (Left Black). Therefore the washer with the oblong
shape on top right part in picture doesn't hold nut steady on the
Swift Shift bracket.

Any suggestions? All I can think of is grind block base back 2mm to
round surface and grind round surface back 1mm to oblong surface, but
that machining sounds expensive. Maybe I could destroy the Suntour
bracket and shape it around Swift shift bracket and JB weld it. Or
better yet, I can check my cheaper stock Simplex down tube bracket and
see how that may work. Rather mutilate that bracket into a rectange
shape. But for some reason, I don't think I will have that choice
since Simplex shifters are cheap and not ratchets.

The Suntour support rods are held by eye shaped slugs in the end, so
don't know exactly how they are held to a fixed position.

Somebody told me they were all shifters were standardized, so I didn't
see the 1mm+1mm differences until fit them on with the proper sized
washers. Standardized? lol

Any better ideas would be appreciated. When the time comes, I'll even
consider a Shimano 7 speed STI, again.


Thanks,
Phil Bailey
