1948 Cadillac Build

I have my Cadillac in piece and ready to start my chassis change out. Looking for some advice on if I should by the Art Morrison frame stub or are there other car chassis I can use to upgrade the suspension? I've read a 96 impala or caprice chassis would work but wanted to see what else is out there.

Thanks

 

Did you see this? I thought a 48 and 47 were close to the same.

Thanks I believe they are the same or at least damn close

 

'70 to '81 Camaro/Firebird subframe works nicely too. This a '46, but the width is similar to the '48.

 

Thanks that will be an easier chassis to find
