I'm missing mine (been 3 days, probably won't be done until Tuesday). I did get the PI cams in it, but on both sides I had a bit of timing chain slip, so I played it safe and brought it to the shop to have a "stang expert" (he owns 3 of them) time it out right. Plus, the tow was free, as my father and uncle know the owner of the shop. This is the first time I've had to "give in" and bring it to the shop. Better safe than sorry though, eh?
