rear end questions

[Torinalth]

well, i'm in the process of replacing everything that can go out on my GT with better stuff, and think that i'll be doing the rear end as well. had a few questions. i believe i will go with the eaton posi differential, and 3.73 gears or possibly 4.10. my car will never be run with slicks, street radials will be the most ever pushed.

question 1- should i upgrade to moser 31 splines? i will never run nitrous or a blower... but MAY at some point upgrade to a big bore high compression block with all the boltons/heads/cams. but i will most definatly do heads/cams/all boltons. with the posi and 3.73 or 4.10s will i ever need the moser 31s, or will i be fine with stockers?

quesstion 2- as i will be doing all the work myself will i need anything otyher then the posi, frpp gears, and axles if i get them.... do i need a new diff cover? bearing kit (are the bearings replaced when the eaton goes in?). this will happen in about 2-3 months but will start collecting items within the week, so i want to be sure on what minor things are needed.

is there anything else i could use as preventative maintanence?

If your not going to run your car on the track you dont need bigger axles. You dont want a Eaton, (trust me).
Question: What is the point of doing all this stuff, are you planning on a power adder, etc., Cauase the stock stuff is more than good enough for a bolt on mods powered car, seeing street use or not running sticky tires.

i want insurance nothing will ever break, period. i want to build it up to be around 350 hp (i can get it with a big bore easy) daily driver with zero chance of breaking. i'll leave the axels, but why the eaton? not going auburn, but i do want posi rear.
