One thing I absolutely can tell...they aren't the same. The picture posted by Jeff (after he looked at 30 or more SJ cars) shows kick panel screws where the underlying "washer" component is fairly large in relation to the screw head. I have two of those in hand and need four more. So, I guess I'll revise my request and simply ask if anyone has four of those exact screws for sale... $$
The AMK picture, and every other supplier picture I can locate, shows a screw where the underlying "washer" component is smaller in relation to the screw head. That is what makes the screws that are available from retail sources different than what I am seeking.
I'm sure you're correct about the manuals, part numbers, etc. But, I want/need the exact screws as shown in Jeff's picture and I have yet to locate those from any source.
Thank you...
