Hi Rotton,
The pads you have are not film accurate. The plate is wrong. But at least in you're in the right neighborhood: they are Rawlings with white plastic and gray padding. There really is no "magic number" or specific logo that will assure you an accurate plate. I've seen Crusaders, as well as CP-46's, that had the wrong plate style.
Maybe your shoulder pad guy has some CP-66's or FB series pads?

I've been recently thinking of ways to help fans identify the right plate design. As we all know, the right plate has the oval "crater" on top. But it seems so many have trouble discerning the differences in the overall shape of the plate. So let's try this:
Do you see how the strap on the front looks like a square? Now imagine placing these squares below the strap on the plate. In the pictures above, you could fit only about one whole square underneath the strap. Do you see that?
There are other common plates that most fans mistake for the right plate (plate "b" on my site) - on these you can again only fit 1 comfortably, but there's enough room left over to where you just might fit 3/4 of a square in there, right?
On the correct plate, however, you could fit 2 squares in below the strap comfortably (although at first glance it looks like even 3 may fit). That's how much more room there is on the correct plate (see plate "a").
