I am getting the following installed in 3 weeks. I have a great shop that I fully trust to do this work so I am not worried about anything like that. I just want to make sure they have all of the misc items needed to install the following:

Mugen exhaust (easy)
J's Racing 4.44 gearing (do I need any fuilds, replacement parts, o rings anything like this first? Does it come with everything I need?)
Mugen thermostat sensor
Mugen radiator sensor
Mugen fan sensor

I'm not looking so much for instructions how to install these parts, more what misc parts are needed, and any tips you might have for me/my installers since some of you have already done these mods.

Thanks in advance for any help!
