I finally got the car in the air to investigate an exhaust leak. Thank you for all of the lift advice, the QuickJack seems to be working great!

Looks like i am missing a bolt. Nothing to attach the nut to, so my question is what to do next? Looking at this picture, does this look like a broken part? perhaps there are threads in there?

Assistance please.

Just went throught this with my car. The Studs for a 2.0 Liter are 8x56mm and the 1.8 Liter motor uses a step thread with 9mm on 1 side and 8mm on the other.

I believe that either are availalbe from European Motorworks in Hawthorne, CA

Here is a pic of the M8s I picked up there

However, the M9 step studs can also be purchased from AASE Sales,
