I finally found my NOS decontaminator, and here it is.
This is the bracket I was talking about. I have another, and I will photo it later.
You said something about the strap model lube chart holder.. I have a supposedly NOS one with F markings. Is this original?
My jeep seems to be weird.. It has the holes for a decontaminator, has the 2 post tire carrier with foot rest, It has the early push pull light switch, DOES NOT have the 4th data plate or 1st aid kit at all.. No evidence of there ever being one either. It also does not have the rear crossmember reenforcements as found on late Jeeps. I don't know what to make of my Jeep.
