Anyone know the AC DELCO part# for the newest TPMS that will work in my 2007 Avalanche? Iv'e looked on ebay and I'm getting multiple part numbers. One seller claims this part #13581558 is 2015 and the batteries are fresh. He warns not to buy old stock sensors because the batteries could be old. The other part# that is more common is #13586335. They are pretty expensive either way but don't wanna buy the wrong ones. Did a search but no luck. Thanks in advance!
