Found I had a missing AC hose clamp just under the drivers side foot well, got another clamp but I can't figure out whether to use a self tapper or a metric machine threaded screw in this? I don't want to tear up all my carpet to find out.
For perspective I circled the jacking point and the two bolts that hold the throttle pedal in place. My car is an 88 targa. The hole for the clamp has grease around it so you can spot it easily.

Thanks!
