It's been quite a few years since I needed an MII converter, so I'm not sure about this. My brother needs one for his pro-street 74. He switched from the big C4 setup over to the MII flywheel and bell so he could run the Hooker headers. But now we need a converter. What do people use for performance converters with the II bell? Is there something specific, or do you just need a certian size case (9", 10" etc)? Any help would be appreciated. Thanks!
