E-Brake Extension - Installation Instructions This picture shows how they go on: http://www.4crawler.com/4x4/CheapTricks/Images/Phase-III/E-Brake-Mod.jpg Block your wheels and release the parking brake. The extensions are a tight fit by design, you can tap them into place with a small hammer and get the bolt in (make sure the bent over side is toward the leaf springs). Then mark where you need the top hole to be and drill it out, the pin is 8mm as I recall on the e-brake cable, a bit larger than 5/16", so 11/32" or 3/8" would work. Then you may need to re-adjust your parking brake cable since it now has a bit more travel.
