Hey Glock 30,must be the warm weather is keeping the replies down. I'll tell you what little I know. I had my dealer install tunnel protectors.They told me they were able to just drop rear of skid,grind a little off the very front of the protectors(not compromising the heat ex protection)and twist and slide them into place.They also put studs in,butthe excessive track noise prompted me to move ones out of line of hard wheels.That helped cut some vibration but the howling is still there as you prob are aware of.I do have extra ice build up on the tunnel protectors,but the extra traction is nice.Good luck with the project and maybe someone will give some more tech help!
