Hello, I can appreciate what you are taking on here. I have done a 32 Chevy Sedan and am now building a 31 Coupe. Lots of wood to replace.I don't know if that crossmember will work or not. What I did was bought and installed a Heidts Super Ride IFS for a 34 Chevy and it worked on my 32. I would think it would probably work on the 27. As a matter of fact I have a brand new, never installed Superride crossmember going on E-bay tonight or tomorrow.They are spendy but the ride is awsome. Later.
