The dealer I bought them from does not have a "Vehicle Finder" on their website, I just ordered 9005's thinking they would fit, the dust cover clearance was all I was concerned with and the SL1s are low profile and have good reviews which is why I ordered. I don't see this being an easy fix, if ever.I'm sorry you ran into that! But that's great that you had a second vehicle to use them in.
Out of curiosity, was the 9005 SL1 listed for your truck on one of our dealer's websites? We don't list the 9005-size SL1 for the 2015-2019 HD high beams for the reason you described, and I'm hoping nobody in our network does!
