Nick,
The bushing that's on the frame side is very rigid, more so than poly, it's rock hard (and I have a pair if you need a pair we could trade or something). If it were me I would leave the new rubber in the new arm and save poly for down the road if you replace ball joints in a set of arms at some point that might be a good time to use poly (a full LCA rebuild).
