[Walt Fricke]

"No click" means the starter solenoid isn't working. Which could be because it is old and sticky. Or because electricity isn't getting to it. So the troubleshooting list for this starts with seeing if you have 12V showing up at the solenoid, and working backward. Or you can see if you have 12V coming out of the starter position of the itnition switch, and work backward or forward depending. I don't recall there being a fuse in any of this, but haven't checked the circuit diagram (but you should do so - this very Pelican website has diagrams you can use, even if not one for '73s).

You'll like the smaller, lighter (and much newer) geared high torque starter, so that's a small upbrade even if nothing was wrong with your 38 year old Bosch. Why couldn't Bosch have made fan blower motors which were as durable?
