Pirate Jacks disc brake conversion kits

I installed the Pirate Jack kit on my 69 Dart last summer. I generally have no real complaints about them. I will admit I was not a fan of the crush sleeves that they use to mate the stock upper ball joints to the larger spindles. I eventually broke down and made other changes (new UCA's with bigger ball joints). But otherwise the component parts all worked fine. I have no doubt that you can also get the same types of parts from Dr. Diff. It really is just a matter of price shopping in my opinion.
