  I have pictures of the before and after x-rays for my past three joint replacements. Your analogy is a good one as I have some modern, high tech parts hidden behind old, body panels!

  I thought my stock Ranchos were fine most of the time. I installed 5100s because of all the conjecture online, and honestly I wish I had left the Ranchos on, only because I don't tow and haul very often. Towing or hauling, the 5100s are much more compliant. However, riding empty, the Ranchos were better.

  Wiring needs to be resolved first. Smoke will just leak out the vent unless it can be closed (after fixing the circuit fault).

  You have posted the same thing in multiple unrelated threads, it looked odd. Further, the GM Customer Service is nothing more than lip-service. I wouldn't bother trying to do anything to get their attention here. Your best bet to call another dealer parts department, tell them you need your part for your truck, let them order it for you based on your VIN.
