More disc brake questions

Correct me if im wrong, but wouldnt this work with the upper ball joint adapters?

That’s correct. But there’s no way I’d buy that kit from POL. Buy it from DoctorDiff

Price is slightly higher, but the calipers come powder coated and you get Timken bearings, not some generic junk. DoctorDiff has amazing customer service, and he has the upper ball joint adapters you need anyway.
