R, Wagon turned out great. I'm the one that furnished the liner for the tailgate window. Also installed the interior in my 60 wagon and found, like you, that it wasn't as hard as I had feared. Interestingly enough, I pulled my 49 Buick sedanette (basically the same as your 48 Cad) out of storage after 10 years, and am back on this build. Given the similarity between these two cars I will follow your Cad build with as much interest as I did your wagon build. I do have the 49 chasis done so if I can furnish any info on what worked for me please feel free to contact.
