1949-54 Chevrolet C4 IFS

Has anyone on here ever used or known of someone using the kit from Progressive Automotive to mount C4 Corvette IFS under the 49-54 Chevrolet cars? I want to know how the quality and fit are and if the car will lay if bagged on this setup. I was thinking about this as an alternative to the typical Mustang II kits. Thanks in advance for any help or opinions.

Here is a link to the kits:http://www.progressiveautomotive.com/sweet.htm
