has the model number been changed to 1860? i just purchased a rack from AP so i went out and bought the tubs thinking they were the 1960's i bought before but when i got home my girlfriend asks me "babe are those the right size, they look a little thinner", so i go to my 1960 model and compare measurements and they seem to be the same..so is the 1860 model the new 1960??? and why are the measurements different then that of the actual sterilite website? i mean the measurements of my 1960 model dont even measure up to what the site has listed. i hope they fit my rack..:/
