TYPE 8 introduced in 1975, used thru 1996 on F100/350, Bronco & Econoline, thru 1997 on F250 H/D & F350. These mirrors were included as part of the Camper Special Package. The mirror head is the same for all, but the Econolines use different brackets than the F100/350 & Bronco. btw: You misspelled lariat.
