JAMAS, my how-to shows the notches to be cut in the front for a flush mount. Cutting bits off the back of the cup holder is only required on certain holders that had more rear mounting plastic. I'm not sure what year Taurus's had which versions of cup holders, but if you find one that seems bigger than 1-din, I think the extra mounting girth requiring trimming should be obvious. To fit completely flush, I can't even place a can of soda in this holder without scraping it down the ashtray area plastic. As I have painted my dash trim, scraping is not an option for me. So I have been riding a 1-din change holder for a couple of years. I'm thinking of switching over to a 1-din chubby hole I also retrieved from the U-Pull-it yard, I think from a Rodeo.
