I have a typical research disclaimer which applies here. When all else fails, I turn to ya'll.
I am having starter problems. Research and tests suggests it is the starter motor. Battery and alternator have passed all tests. I got under 'er and found dirty/corroded solenoid connecter from the battery. I cleaned this thoroughly but also found the nut was not present. Went to Autozone and they determined I needed a 3/8" nut. I asked if this should not be metric as it is a Canadian build. Well, come to find the 3/8 16 did not fit as I suspected would be the case. Am I wrong or right?
Thank you.
What is the model year of your LD? Here is a link may be helpful:

G-30s of your vintage were mostly SAE (Society of American Engineers) hardware. Chevy didn’t change the hardware based on the country of origin.
Your rig was built during the transition period and may contain a mixture of metric and SAE hardware. My 2001 Jeep Cherokee has the same issue. requiring carrying twice as many wrenches and sockets in the tool box. Our 2003 LD is mostly metric, it still has some SAE hardware.
Did you try a 3/8-24 fine-thread nut?
If that doesn't work try a 10mm x 1.25mm and a 10mm x 1.5 nuts, they have a similar diameter to 3/8” SAE nuts and are easy to mix to get mixed up.

This is a handy tool to have, along with a caliper for diameter:

I had a class B with the same Chevy motor that left me stranded one day cause starter wouldn’t work. Called for assistance provided by my insurance company. When the fellow arrived he went under my van with a hammer and gave the starter a good solid smack. It then started right up.
He said he was able to get quite a few Chevy trucks started this way. Apparently something can jam up in the starter or selenoid as the starter ages. I promptly replaced the starter after that episode and never had the problem again.

Thanks as usual Larry. I found what I needed and all is well. Starts like a champ with no hesitation. I really appreciate your constant input.
