Yep, that's what I was thinking as well. Those LCA mounts get us 2wd guys every time. Even the stock manifolds get real close. My Schoenfeld's clear by miles.From what I've read on the Facebook group for LS swapped OBS', the Speed Engineering headers do NOT fit 2WD OBS' without some bending/modifications. They DO fit the 4WD OBS though. Most on there just suggest using the Schoenfeld headers for less headaches.
