modifying mount?
Hi,
Afraid I don't know about modifying different rack mounts safely.
Here is what must be a common situation...
So, what is the usual method to make this fit?
Red circle drawn around eyelet is 2 inches lower than where the slide out twisted bars extend out to.
What is the usual method?
Use the eyelets somehow to mount the racks?
Or instead mount new attachments with eyelets onto the stay?
By the way, the stays are about 0.640 " diameter almost round but not exactly round.

If I'm right you're supposed bend the 'slide out twisted bars' to meet the eyelets.

The rack seems to be mounting a little high. It may be possible to drill a new hole in the rack, at the hub fixing point, to lower it. The lower you can mount the rack the more stable the bike when loaded but take care to keep adequate clearance for your heels and derailler. Judicious bending of the x2 fixing plates should take care of any remaining misalignment.

+1 Bend 'em
Probably not the best idea to drill the rack. The rack would be weakened and might be prone to failure.
It looks like a 700 C rack on a 26" bike. Not horrible but it will make the load carry a little higher. That's not ideal but not catastrophic either.

+1 Bend them, extend them, and angle the rack back a little further so that is level & parallel to the ground (looks like the rack is leaning forward right now). The arms will make a nice little arch.

Yes it's an old 700c rack (Blackburn off a Cannondale tourer I sold) on an old fashioned 26 long wheel base mountain bike.
Is there a pictorial somewhere about bending?
I have a large vice on the workbench which I'm sure will help.
2) I'm not sure why they look like leaning forward but they do. And yet a bubble level is laid along it is centered. I suppose if its bubble level then its level like I want?
Thanks!

You won't need to use a vice, loosen the bolts almost fully on the rack side side of the arms and then bolt up the front ones. Then find the sweet spot for length and they will arch on their own. Then just re-tighten on the rack side.
I couldn't really find a good picture in google, but this is close -

Ok, thanks!
Yes that is going to work.
I never had trouble with touring equipment before.
Lots of trouble with other stuff. Once, after a road stop in Mexico I started out again and two hours went by before I realized why the scenery looked familiar. I have a two dollar compass on a string now.
