You will only have three if your car had a radio installed. In the unlikely event your car had no radio at all, it would have only two grounding straps.
The two main straps attach to the rear lower valve cover bolts and then to the firewall. The radio-installed-only strap is very short and connects the passenger side inner fender to the frame rail. The proper location is right under the battery tray and there should already be a small hole in the frame rail which helps you find the proper location.
Additional grounding is accomplished by a small wire from the negative battery cable which connects to the radiator support.
An additional grounding device for radio equiped cars includes a brass star wheel installed inside the passenger side front wheel hub which grounds the spindle to the lug bolt hub. It is intended to disappate static electricity which accumulates by the turning wheels.

Checked the manual? Nah, that involved reading, thinking and, getting smart. I cheat and open the hood. Was no ground straps in there the day I drove it home from the dealer. Keep saying the 72 is a little odd. BTW, still haven't seen a true 72 TCS solenoid to check it out. Still think those are backwards also. Gone past Tuesday again.
