First off you need to properly ream the knuckles. That’s just dumb and completely unsafe running them like that, sounds like the shop doesn’t know what they are doing if they cant do a simple job like that, you go slowly with the reamer while checking fitment. The bar roiling is typical of this type of steering; JCRs sell nylon type washers to go under the tie rod ends to keep it from doing it as bad.
