[Does someone know this kit from AutoACSolutions?]

I have a very similar kit, well, it uses most of the same major components. the controls are different. Its installed on a 71 and works quite well.

However, and with the presumption that the idea of paying for a kit is to allow you to install all consonants without having to run all over town looking for misc small components, at that it failed.

The fit of the "suitcase" under the dash is horrible, this is a universal device, not engineered very well in my estimation , The instructions were completely useless.

Just about everything required massaging to fit and, for example, there is a door that switches from vents to the defrost, its just behind the 4 outlets on top, it has a built in seal that got stuck to the housing preventing the door from working at all, had to tear off the gasket/ seal piece by piece and fish it out via those 4 vent holes.  

Overall, a terribly engineered product specially for the cost, but hey...you want working AC right?

 

[Anyone have experience running E3 spark plugs?]

BP6ES/BPR6ES anything else is a waste of time and money.

OK, maybe I'm being harsh, depending or your setup where a different heat range is needed you might want to try BP5ES or BP7ES.

[240z L28 Cam Profile - 3x40dcoe]

Kinda big....imo

See enclosed pic, this is what I have. ( carbed L28, dual Webers)

good torque, I can cruise at 5th at less then 40mph at just over 2200 rpm

Explosive mid range, starts off at 3300 rpm+- and doesn't quit. wouldn't consider or want anything bigger for street use but that's just me. 

With your triples...I would be afraid that it will not be very street friendly.

 

[260z 2+2 Windows]

Tons of them on ebay, quite cheap.

[280z/zx harmonic balancer]

Need one, must be reasonable.

[Getting rid of that rat smell]

An ozone generator is your best friend here, you can build your own for peanuts, a kit on ebay is less then $20, you will need a case (50 bmg ammo can works perfectly) and one 4" fan, ($10+-) 15 minutes of operation will be more then enugh to get rid of just about anything.

[Window Regulator rolling piece]

Does anyone know if I can only get the rolling piece and install it because I don't want to buy the whole thing when only one roller is broken

They are easier to find then you think..I got a few spares if interested
