Hi just wondering if anyone knows the exact factory size of the 91-92 taillight decal. I have ordered a new decal from a company that sells specifically for the replacement of that decal and they seem to be having trouble with the scale. I have recieved them being too small twice now then my original that I have. Mine measures 14-11/16" long X 1-3/8" tall. Does anyone have any info on this? And is the size that I have the correct size?

Thanks
