First time I read these reviews today. Great info and fortunately most of your mods have went well. Many of my mods have had complications. I notice you plan the Quaife soon. If I had to do it again, I think I'd just have my mechanic remove my stock housing/diff and send it to Harold at HPA for the install to make sure someone with experience was doing it.
