I have just noticed that the front lower wishbone bushes I got from Resto Country are different. Two have "3 x dimples" (the same as the pic in the Gregorys manual) and the other two do not. Can someone tell me the correct way to install them. Is this something to do with the RTS package? I recall reading somewhere that the dimpled ones go to the rear and the others go to the front of the wishbones. Any feedback would be appreciated.
