so if you already bought the plus four degree timing advance rotor,
thats actually a really easy install.. i personally got a thin edged flat head and just worked it around the timing cover.. it will be stuck on there pretty good, especially seeing its a part that doesnt get removed often..
i also used my air gun and its put on (rotor)lefty lucy righty tighty.. so its not in reverse, which is what i was wondering once i had everything apart and having both service books, neither was very clear anyway lefty lucy to back it off and most likely you should be able to reuse the gasket..
you'll find very little oil behind this cover but there will be some.. having a rag just under where your working should be more than enough..

hey splash,
so i personally havnt done the factory pro shift star mod, however i found a how to: on a slightly different setup, but im sure it would be very similar to our's.
