Since your sir supply lines were detached I recommend starting by removing the air springs from your 2010 GMC Sierra 1500. This will allow you to check the condition of the air bag springs to determine if they are even usable. Typically when an air spring is run without any air pressure the spring can fold on itself and become pinched and damaged. It will also allow you to find any manufacturer tags located on the mounting plates. You may also find some numbers stamped into the rubber portion of the air spring as well.

If the air springs are still in good condition you should be able to replace the elbow with either the 1/8" NPT # F3128-1 or 1/4" NPT # AL21837.

Please let me know any numbers or tags you find and I can confirm the exact parts you will need.
