This if from the Fj62 Desmog Thread. That thread should have all the info you need.

Dorman 090-099 plug m26x1.5 is the plug for the exhaust manifold. need 1
Toyota 90340-14001 plug for the air rail. need 4
Dayco 22528 is the belt. need 1
Dorman Help 02254 cap is for the intake. need 1
Dorman 555-118 expansion plug instead of an egr block off plate. need 1 check the specs
High temp thread sealant
1/8 inch or 3.5mm vacuum plugs. need 7
Delete your cats anyway you want.

Did a little research tonight because I’m bored and figured I’d try to keep the confusion down a bit. I personally have not tried all of these. I am going off of my experience and others with the short belts ~53” and @Old Nick belt pictured on the previous page ~59”. The first 2 bypass the alt and the second 2 do not. The Dayco 22590 is the only belt listed that I’ve never seen used but it will be the next belt I buy. FWIW.
