Very nice product, but I have one minor complaint. Since this bolt kit is listed for 79-95 Mustangs, I figured it would be more specific to those cars. What I mean is, there is a place to attach an engine hoist located on each side of the engine. It's just behind the power steering pump on the driver's side and near the firewall on the passenger side. These loops are attached to the engine by the stock header bolts. The stock header bolts first lock the headers in place then have a protruding bolt that you use a nut to attach the metal loops. These came in handy when I installed new engine mounts. With this Stage 8 bolt kit they have no hardware for attaching the engine hoist loops. That sucks
