Is the rack in the photo at the end of it's travel? The rod end looks really close to the rack case.
Usually you look at the front end geometry with all of the components set in a straight ahead position. That rack looks like it is at the extreme end of its travel. Do you have a full on front picture? If everything is set up in the straight ahead position in that pic I'd say you are close enough. But it doesn't look like you will have alot of turning capability.
Speedway motors has a gauge set you can buy to check your bumpsteer for sure. One look at it and you will be able to make your own and figure out how to use it. ( i remember you are a tool and die maker
Hope this helps, mikey
