1937 "120" Flywheel Bolts

I had my 1937 "120" engine rebuilt locally several years ago. I had a new ring gear installed on the flywheel and had it resurfaced, I've just realized that the shop never returned the bolting from the flywheel to the crankshaft and the shop is now out of business. I was able to purchase the correct 7/16 x 20 bolts from "Merritt" but since I didn't take this apart I was wondering if lock washers are needed on these bolts? My master parts list doesn't list any lock washers, the part number for the bolts is 300162. Just trying to avoid a future major problem. Thanks

I'll confirm next weekend when mine is out, assuming the hacks that worked on the car previously didn't mess something up! (Whoever worked on my car in the past replaced many of the original bolts with whatever happened to be at hand that fit in the hole. Kind of frustrating, and I find more problems the more I look)

If I remember correctly, there are six bolts that hold the flywheel to the crank, and a locking tab for each set of two bolts. I seem to remember they were a royal pain to bend once the flywheel was installed!

Edit: the parts book confirms, three lock plates, PN 300163.
