First of all, thanks to everyone for your comments! It's so cool to hear from people all over the world and get their knowledge. Much appreciated!
Phil, I have been looking for parts in Canada but unfortunately we just do not have the demographic to sustain such a unique thing. I've been using RockAuto for several smaller things (plugs, gaskets, etc). It is pretty good since it has both the 1940 Dodge D14 and the 1940 Plymouth P10! I actually just found the exact parts book you've shown for $15 online (plus $30 shipping... man living in Saskatchewan can be costly haha). I like how the book shows the various years and if the part numbers are the same. This will make it so much easier to maintain!
Andy, I am astonished by your attention to detail on the differences between our cars (straight vs dipped bumper, chrome windshield trim, etc). I'm fortunate that the body is all there (I think haha) and I shouldn't require any panels and should be able to fix/clean the few small rust spots quite easily. My grill is attached by screws going through the front (same as yours). I do not have a rear picture of the car readily available but I'll make sure I have one for my next post! Your back end is quite a bit different. Is the two piece bumper stock from a different year? Or is that a new/rat rod kind of piece? It looks very distinct, especially with the dual exhaust.
1950SpecialDeluxe, do you know if there are other groups in Saskatoon for people with old cars like ours? I don't see too many of them kicking around but it would be awesome to meet other! Also, great pic in front of the Bes!
