Engine mounts and trailing arm bushings

[Thealien]

I am doing an LS swap to my 2 wheel drive Blazer. I need engine mounts to bolt to the adapter plates. I am changing the trailing arm crossmember and plan on changing the trailing arm bushings while they are off.

I do not want polyurethane I want rubber.

I bought some Moog Rear Control Arm Bushings K5161 at the recommendations of a forum member. But here is what Moog says?

"Thank you for contacting us we do not have the trailing arm bushings for it."

So I am doubting what I purchased will work.

Does anyone have a source for quality rubber engine mounts and trailing arm bushings.

Thanks
Mark
