Starter Replacement 1982 GMC Jimmy Diesel Sign In

I was recently replacing my alternator, when I managed to arc one of my lines. Part of my power went out: my headlights worked, but my truck showed no signs of power when I turned over the ignition. Maybe I blew out an inline fuse?
I thought the issue might be my starter connection, which occasionally shakes loose on my old diesel. I went to tighten the cable connection and ended up breaking the bolt right out of the front of the starter.
I'm assuming that my entire starter now needs to be replaced. I've priced them online for around $130.00. However, I don't have the tools for this sort of undertaking. How MUCH money should I be looking at to have my starter replaced?
If anyone has a good idea as to a figure I should use as a good benchmark, I'd greatly appreciate it.
Have a good one.

As for the lost of power after you shorted the wires; its likely caused, as you suspected, an in-line fuse to burn out. These fuses are call fusible links and are made up of short sections of wire, 2 sizes of wire smaller then the wiring of the circuit it’s protecting.
On this year of truck the links are usually found connected to the starters main battery terminal; I guess the one you broke. At times these wire links may not visually look to be burnt because the insulation will be intact. Give each one (two or three) a firm pull, if the wiring is ok you won’t hurt anything but if the wire is burnt the insulation will feel like a rubber band and eventually pull apart.
Depending on what accessories that came on this truck you may also find a plastic junction block bolted to the firewall containing another set of fusible links.
It shouldn’t take a technician much more then an hour or so to remove and install a starter motor.
There is a chance though that you won’t have to replace the complete starter, just the starter’s solenoid? That’s if the starter were functioning fine before the broken main terminal, this terminal is part of the solenoid. The starter motor will still need to be removed for ease of replacing the solenoid but you won’t have the cost of the complete starter; solenoids sell for 10 or 15 bucks.

This is a generic diagram of a starter but close enough for you to see that the solenoid is replaceable
