Need help ith identifying a part

I have learned my lesson when I asked the manufacturer of a suspension kit if it included everything I needed. I bought it and it didn't. My stupidity for not doing more homework and trusting a company.

I am looking for part numbers for a:

1975 Plymouth Duster lower control arm shaft bushing. Poly if possible but rubber will do. UAP is puzzled and a few searches has resulted in nada however that may be due to me.

Thanks
Ian.
