Fender Blacktop Jaguar Pickup Rings

[izwald1989]

Hi Guys,
Currently ripping all the electronics out of my beloved Blacktop Jaguar. I'm upgrading all the parts;

CTS Pots
Switchcraft Jack and 3 way switch
Seymour Duncan SH1s

and I ordered a pair of cream pickup rings because the pickups are zebra and I like the look. However when they arrived they were too big for the pickguard and they are slanted as if for a flat top Les Paul, there's no curve on the bottom. I'm pretty sure the drilled holes are not fitting either. I know it's probably a quick fix or something very simple but I can't see it for looking.

I've been googling to see how to measure the rings but I'm wondering if someone here on the off chance has has prior experience and can just point me in the direction of where they bought them from to make it a bit easier. Any help is much appreciated!!!
Cheers
G
