Sorry for the thread-jack again Speedstream.
Just got off the phone with Chuck at Pace a little bit ago and was told that GM has released the 19155067(
which is the kit with AC, but they break the kit down to create the 19155167 NON-AC kit we are looking for) from backorder and they should be arriving by the end of the week
I shot out a couple emails to a few dealers to verify this info, but it sounds like we may be back in business soon
