Hotchkis bolt on subframe connector

I think your buddy is confused. The Hotchkis subframe connectors don't bolt in. They also don't generically fit all "a-bodies". There are two different versions, one for 108" wheelbase cars and another for 111".

Other than that, Hotchkis makes great stuff. But on an A body I wouldn't spend the money on subframe connectors because they're basically just straight tubes. You can make your own for much less.
