Hood mounted turn signals NEEDED

The kind that 64dartwagon has are the 73 and up ones the ones that mount from the underside that Suregrip391 needs are on 72 and earlyer. besides mounting from the underside they are shorter and rounder that the 73 and up ones. Im with TheBestCar I would bust out the welder before paying that much for something that ends up in the $1.00 bin at a swapmeet.
