A bodies came with them front mounted. But that can interfere with a sway bar. The can be mounted at the rear with out any issues. Just make sure the bleeder is at the top.
I'd like to add,Almost, without issues,Cuz you have to be careful of where and how the hoses are routed, cuz you are re-engineering, and it's your responsibility to make sure those brakes never fail, due to your not paying attention to stuff.
I'd also like to add that I think my 1980 F-body has 'em on the rear side. I like them on the rear.Why,IDK. Why do I like 1959 Belaire tailfins better than 1960,IDK. Why do I prefer Redheads,IDK. I have no problem figuring out why I like my wife. Life's just like that....
