Hi,is there a difference between the HQ and the HZ inner guards,I am getting my guards ready for air conditioning and I salvaged the drivers side off the HZ and another passenger side I had under the house and there seems to be a difference, the one I think is a HQ has some buttons to hold on the dust shield but a lot of staples , where the HZ has just the buttons holding the dust shield,any thoughts?. Cheers
