Boling Brothers Brakes Question

[mgm60]

I've installed the Boling Brothers Brake Kit on my 36 Ford Roadster. Replaced 48 Ford backing plates with the 39-48 Kit (picture 1). The brake shoe retaining springs sticks out slightly past the edge of the 1 3/4" brake shoes about 1/8" (picture 2). So the spring retainer interferes with the backside of the wheel studs on the drums (picture 3). Has anyone run into this problem and if you did, how did you fix it? Already called Boling and all they could do was verify I have the right #8 pins for my kit. Thinking about putting a washer on the back of the backing plate where the retaining ring pin goes through but that will cause the spring to have to compressed even more.
