Identify this Hays clutch disc.

Would anyone have information on this clutch disc, or perhaps could reference an old Hays catalog? Hays has been taken over by the Holley group and have no info.

Of course, I realize it is an 18 spline, 11" disc with organic friction surfaces, I'm trying to find out if this disc has marcel or if it is a flat plate carrier? Looks like it mat be a street strip disc?

This is for sale one Province over from me, so far I've not been able to reach the seller for any information. I've also tried numerous searches using the part number on the box and turned up fruitless.

Thanks in advance for the help.
