small ball joint vs big small joint

You can buy adapter sleeves from Dr. Diff, to adapt the small ball joint to the 73 and up spindles.

Yup, that's an option too! Not sure how that works out for strength, but the upper ball joints weren't ever really an issue.

I didn't know that was an option, man ,dr diff has some good stuff.. thanks

Yes he does! Cass is the man. I have a bunch of stuff from him on my cars, his brake kits are awesome.
