*DISCLAIMER*
I have done my best to compile this list accurately, but please do not rely on this information as complete or accurate. DOUBLE CHECK THE PART NUMBER AND DESCRIPTION BEFORE YOU BUY ANYTHING FROM ANY VENDOR. FURTHER CHECK IT IS THE RIGHT PART FOR YOUR HUMMERS YEAR/ENGINE TYPE/ETC.PARTS AND PART NUMBERS CAN AND ARE SOMETIMES CHANGED/ DELETED / ADDED/ ETC. Reply here or message/email me if you find any mistakes. This is a obviously a work in progress but at least you can search now by part number for various GM part sellers to get the best prices. Searching in Ebay also works if you search both in the title of the auction and the description for the part number. Please also let me know if you find parts you want added and I will edit this post.
*END OF DISCLAIMER*

Please note that not all the parts listed below are just for the H3, some are universal (such as a first aid kit) and may fit other vehicles, but all are official GM parts. I will continue to add parts as I get them.

Well it's far from a complete list is sure as hell is a good start!! Thanks Rob!!!

 

I will be gone from Jun 21 through Jul 05 on vacation. It is unlikely I will be able to update this post while I am sitting on the beaches of the various Hawaiian Islands we will be visiting.

 

Rob,
Just go away! We're not interested in your HI vacation.[:@]

 

Don't worry, I will be gone soon enough . Problem is, I will be back, I am hard to get rid of.

 

Back from vacation, will be updating more frequently now.

Rob

 

Quite the LIST Rob!!!!!

 

Can you verify that " Hummer H3 Roof Marker Lamp Package - Includes Hardware Kit 19166038 " refers to the new replacements (no wind noise)?

 

I will check and advise, if I find it does I will link the vendor

 

After checking two sites, I found one that lists the same part number for both 2006 and 2007 models. The 2006 listing of that part number includes the verbage "Includes Hardware Kit" the 2007 does not. I am linking that particular site so you can check both of them. As to the "no wind noise" I am not sure. If you would like I can do further research by checking some other websites for that part and seeing what I can find or perhaps we can find someone who has bought it lately. I assume that since that part number is used twice that there is a difference if you order the 2007 one but I can not say for sure. Maybe it lists 2006 - 2007 simply because it fits both... if that is that case why the different descriptions? Kinda odd.

The close up pictures from the link look nice. Also, that website is high. I found a different vendor selling that part number for $458 and some change.If you want the address of the other site selling it cheaper let me know, I didn't link it because the description is morevague than the dealer above.Let me know what you find out and if anyone else knows I can add comments to that part.

Thanks,

Rob
