What brand mounts did you buy, are they stock replacement rubber or polyurethane?
Which mount are you referring to specifically, the radiator support mounts, the front cab mounts or the rear cab mounts, as they are all diferent in shape and size.
you also have a difference between the 2 and 4 wheel drive versions of all of these mounts, if the rest wasn't confusing enough.
I have the information you need for all of this stuff.
I'll see if I can scan a couple pics for reference later.
