I am trying to put together an order to include the 7424 XP. My truck is fairly new and besides some slite webbing introduced by the dealer, I dont believe I have any heavy paint corrections to make. Based on what I have read in this forum I think I should be o.k. with 5.5" Lake Country white and Grey pads to start with. Is the W67DA backing plate that is included from ADS ok as far as size goes for 5.5" pads or should I use a smaller one?
