1962 Crankshaft Pulley. Is it wrong?

I bought a crankshaft pulley (2 groove no AC) a couple years ago and just got to using it.

I initially put it on, lined up the holes and torqued it down. Thought it was curious it didn't sit flush agains the balancer.  After a while I noticed I kept having to torque the bolts down. Again & again. They wouldn't reach 30 ft pounds.

Woops.

I mis-read the '62 manual. The manual says 20 foot pounds. Not 30.

I took the pulley off and its bent just slightly. Photo attached.

Also noticed many of the photos I found had a "ring" or shim or plate in front of the pulley. The shim/plate isn't really listed in the master parts manual, except to say its included with the pulley for AC cars:

So I found a shim/plate. It doesn't quite fit over the front of the pulley. The "lip' is in the way. If I put the plate over the balancer, it fits flawlessly.

Regardless of the bend I think the pulley I have is either the wrong year or not a Cadillac pulley. I've looked at other 59-62 pulleys and none have the "lip" that mine has around the circumference.

Want to reference this thread as well:

I measured the crank area that the pulley is supposed to fit onto. It measures 50.75 millimeters. Roughly 2 inches in diameter. Photo below.

The pulley inside diameter  I have measures 46 millimeters. Roughly 1 13/16 inches.

This tells me there is 5mm difference and probably no amount of bending back is going to make up that difference.

I found another 2 groove pulley and hopefully it arrives this week.

Thanks for listening.
