I remember seeing the thread about you stretching the cab into a crew cab. I haven't seen the pictures of how it all turned out, but if those first pictures are any indication of your fabrication skills, in my opinion, you sir can put a class 8 air ride under a Chevette. I wish I had your skills. Keep us up-to-date, as I thought about this exact same swap before I found out how good my truck ran and drove.
