Strong Arms bushing. Is this right?

[camarosaurusrex]

I got around to putting these on my 68 Camaro and get the upper arm on the driver side and happen to notice that on the right side of the arm it looks like two bushing are in. the left side of that arm only looks like one is in. I hope the pictures can better explain it. After noticing this i looked at the passenger control arm to find that both sides of that arm look the same again i hope the picture helps. Is this the way it is designed? The other issue I have is in the picture of the left side driver arm that bushing wouldn't compress any more to be flush like the other sides
