They are a direct fit, look just like the stock one's. I would get the 74 just incase because I heard there where two versions of the injectors on the 75. The other won't fit.
BTW they are only $44.95 at carparts.com and $7 to ship, no tax. If you do a search on Carparts.com coupons on a search engine, you will find a coupon code for 10% off. I just bought some last week for $40 a piece.
