I have a 351-W front cover.It has the boss for the dipstick(gotta drill it out though)as well as the fuel pump boss,its std rotation.only problem is the oil drip rail on the back side has been cut off for gear drive clearance.I took it off my sprint.If your interested shoot me a pm.
I just popped the hood on my '93 Bronco & you can definitely see the difference on it. I still think you should get one specific to the year of the car just to make life easier!
Glad to help. With the dozen or so timing covers Ford cast for the small blocks over the 40 year run, things get a mite confusing.
