Description

Cap that fits GMT800 trucks. Designed specifically for my Avalanche, should also fit Silverado, Tahoe, Suburban, Sierra, Yukon, and Escalade from 99-06. Bought a truck that didn't have a cap, and no stores had them in stock near me, and nobody on here had designed one yet, so I dusted the cobwebs off my 3d design skills and whipped this up. Almost perfect replica of the actual cap. Please note, it still needs the rubber membrane to fully seal. Maybe just cut one from a piece of scrap rubber, idk. And keep in mind the effects of brake fluid when it comes in to contact with different kinds of plastic. Maybe I'll design one that seals without the rubber. But for now enjoy this, hope it helps.
