BMR K-Member and Lower A-Arm Fitment?

I have a 95 Z28 and I went to install and tubular K-Member with my new motor today on a lift and what not and the holes for the k-member in the front didn't fit at all. I had to grind them out for the K-Member to sit flush anyone ever have this issue? Also the washer that is ziptied to the rear that is left in that position correct? I also have tubular lower A-arms for it. The rear part of the arm the silver part I cannot fit the metal sleeves in it. The are way to big for the arms. Any possible way the put the wrong attachment on it? Anyone ever have issues with this.

Thanks A MILLION,
Tyler

I have searched on the problems we had today and couldn't find a single thing about it. All I know is BMR sent Tyler the wrong A-arm endjoints. I'll post some pics when I get to the shop tomorrow.
