87 13B Rebuild rear rotor is too tight to housing for springs to fit

I have a 1987 Mazda Rx7 and this is my first rebuild, all my parts I've gotten from Atkins, and in the middle of the rebuild. The first half went off seemingly without a hitch. I'm attempting to put together the last rotor and it slides in fine and the apex seals are clearances correctly but I can't get the springs to sit in properly, it feels as though the apex seal is too closely pressed to the housing and the spring can't fit between. This is my first rebuild and i can only assume I'm doing this wrong in someway, the long springs get caught on the smaller spring notch and can't move past. Help is appreciated.

make sure the corner seals on ththe bottom side of th rotor are still in alignment along with the springs, also try rotating the e-shaft....get the rotor in a different position see if it helps. Ensure you haven't been given wrong springs......lift apex seal higher and then try seat the springs. Try seat the big spring first then the small see if it makes a difference....awkward but doable.

It takes some wiggling to get the long spring in place and past the lip of the short spring. I like to go in at a fairly steep angle then straighten the seal up as it starts to slide into the slot. Sometimes needle nosed pliers are needed to move it up and down until it final wants to sit in place.

You are placing the springs open end toward the apex seal, right?
