Hey everyone I think I got what everyone is been asking for all this time.... But I have bad news though...
I did my research through the forums and nothing, nobody knows a GM Part #, so I took it to the dealers. This dealer of all of the ones I called told me that the price for the Accessory Rear Compartment Tool Kit is $397.00 and the GM Part # is: 25621889.
I had to tell you guys this morning because I been desperate for one, I replaced my air ride compressor the other day, and I wanted to see it work, inflating something,,, But I think the price is outrages,,, unbelievable...
Days prior to this I went to Wal-Mart and I got the hose fittings, but I don't have the adapter that will connect from the inflator valve to the hose, IT SUCKS!!
Well there it is if someone can find a better price let me know, I'm not going to pay $397.00 for a hose with a gage.
