I think I have proven myself wrong on the 57. I have found a listing for one in the parts book. I thought all 57 2 door wagons were sedan delivery style only but I don't think so.
Anyway, the following answers are still wrong---
55-60
57-60
58-60

There seems to be no 59 Pontiac 2 door wagon. It appears there was a 55-58 and a 60 but no 59. I think we discussed it here maybe 2 years ago and everyone pretty much agreed it must not exist.
Nothing at all about it in my parts book illustrations either.
Strange thing, makes you go hmmmm
