I believe those fasteners should be "slid" into place on the part that was removed first (should be a slot to receive it), then line everything up and it should snap in.
@Soupy you can still buy and I would recommend to buy a Deno rebuilt starter vs a carquest reman.
Since I'm still rolling with the original starter and alternator (now over 223k miles), I was looking into purchasing the two parts...
Denso (remanufactured) starter: 280-4169, $117.99 through Summit
The rig is looking great, Soupy!

Looks great. If I was closer, I'd get the 3rd row headrests from you.
I'm gonna drain and fill all the fluids (trans, rear diff, transfer case) and see if that helps.
You may also need to check the vacuum diaphragm on the front axle disconnect for movement or leaks. I had to replace mine due to a tear in the outer section. The system also usually needs to be exercised, especially if it wasn't used much.
You'll find some more troubleshooting tips here: Pajero Blinking 4WD
I'll send a PM about the headrests
While you're under the rig, you'll want to lube the shift rod on the freewheel assembly.
Check out page 26-37 in the below link. When you're under the front end, you'll see a dust boot. On the driver's side there is a small tab on the end of the boot. Use this to pull the boot back to expose the shift rod. Apply some grease and return the dust boot to its original location.
(GL-4 in the transfer case, GL-5 in the diffs., MM SP-III in the transmission.)
Cheers
