Ahh, Yes, Jeff brings up a good point...and that is that sometimes a single strap is used, but is bolted to two separate areas, two separate bolt holes instead of one. Don't know if that is that case in the picture above...Hard to tell from the pic. Usually, straps used only one hole, and the one bolt went through both strap holes, but sometimes a single strap will be bolted to two separate areas as have been found on some cars. Good catch Jeff. As you can see from the Metuchen w/AC car pic, That particular Metuchen car actually used 3 straps. As I said earlier, It's very hard to tell the rhyme or reason of the strap use...It was probably up to the guy on the assembly line. I don't think that it was Plant specific or at least, I haven't found any evidence to support that theory.
