Well the results of my Right or Left query are in:
It seems that starting with the '53 model the spare was definitely on
the left with an indented fender except for one report on a Canadian
version, and also on a 3800.
Prior to that it looks like at least with the 3/4 ton 3600 model factory
version it was on the right. The 3/4 ton has enough space between the
cab and rear fender to mount it on either side without an indented
It doesn't look like the 1/2 ton 3100 had a factory installed side
mounted spare in 1949-52.
The problem is that the aftermarket side mount bracket fits right or
left. So I guess it is just a matter of personal preference.
