Just a follow-up note regarding the proper bolt when mounting the tire carrier. When I first try to put the parts together after receiving the mount from Dan, I went to the dealer & checked on the bolts between the SUV & SUT, both for MY 2005. The dealer’s list showed that the SUV uses M12x1.75x55 (11518590) & the SUT uses M12x1.75x65 (11589048) as stated above, and the same specs were confirmed by gmpartsdirect.
So without even measuring the length, I worked off the assumption that my 05 SUV were fitted with the 55’s. In any case, I passed by the dealer as they finally got some of the 65’s in and I wanted to replace the single class 8 ½” with the correct M12 one. To my surprise, the 65 bolt is exactly the same length as the original bolts on the SUV, at least on my truck, so may be GM decided to simplify parts and/or minimize mistakes by using the same bolt (wonder why the dealer didn’t show this).
Thought I post it here in case someone plans on mounting this carrier, and you may already have the correct bolts.
