control arm bushing

so the upper control arm bushing are totally blown out on my 95 Chevy 3500 2wd. Just wondering what everyone one is is using to replace theres? The guy I got the truck from gave me some bushing but from reading it says I have to reuse the factory shells ( I have never seen that before) I have only used stock replacments and Energy Suspesion bushings..
Anyone use these?

We prefer Moog or Energy Suspension.

OK. thanks

my uncle found that the front suspension of his car is not very heathy. Everytime when he drive on the bad road, he can hear a lot of clunk coming out from the front, and when he drive over some big speed humps, there will be a long noise comes out. is the lower control arm has given up? any response is highly appreciated. thanks a lot.
