naw just replace the fabric part...
15mm 12 point socket? or 6 point socket...
and naw man grade 5 is fine... and a nut is not going to care about the ever so sligh difference of the 9/16 and 14mm...
im doing the rear main in my 90 manche now... although i stripped the motor, tranny, xfercase, and all out... painting the engine bay... painting the motor and replacing everything seal related except for pulling the head...
if all you want to do is the rear main seal then i recommend replacing the oil pan gasket... but the oil pumps (on the renix anyway) are lik $80 frickin bucks... since this is all your doing i say replace it too... youll have to pretty much pull the motor to do it if it ever fail's in the future... me... im not... all my moneys already going everywhere else and i ran out... lol... if your motors stock then run a stock pump... its lasted this long right and still counting... why buy aftermarket... aftermarket are for motors creating more heat and near more oil flow...

Actually there are no plug wires either. The plug boots connect directly to the coil rail. All of this has been replaced, with the exception of the coil rail. Each coil pack controls 2 cylinders, so if a coil pack was bad, misfire would affect 2 cylinders. That isn't what I am seeing. I have done most of the basic things suggested on the forum, i.e. tune-up, TPS, CPS, etc, with no improvement. I was hoping someone would be able to share their experiences of a successfu diagnosis of a similar problem.

Also just because a coil is ran to two plugs and your only misfiring on one cylinder doesnt mean it still not a coil... Within the coil there has to be something that determines which if the two cylinders to fire to... I do believe they are all the same coils on the 99+ so a simple swap of two coils will tell if its a bad coil or not... if its bad the misfire will move to another cylinder... Also research a injector wiring causeing the misfire... Seems to be common and a common ground out on something but I cant recall...

x2 - although mounting lights that close to the hood is going to put some wicked glare off the hood when you turn them on.
