front roll pan spacing

[tphsmith]

my truck is a 72. i got this front roll pan from e-bay, says its for a 67-72. the roll pan also came with a bumper radiator deflector. looks sweet. now looking in my guide catalog,(LMC) the bumper radiator deflector was only used for 67-68. so my question is, I'm wondering ? is there a diffrence of the spacing between the the very front bottom of the fenders from a 67-68 to a 72??? when I measure my 72 where a roll pan would go, center of this location I measure like 66 1/2 inches. can I please have someone measure thier 67-68 between fenders where a roll pan would go and tell me what the distance is on your truck,, PLEASE
