I am looking to replace the pittman arm on my car. (Manual steering, manual drum brake, 383 HO). The arm I have now is worn, the part # 1858018N1599132. There are many pittman arms online and very few that have the same curve as this one does. My father suggest this one from P-S-T http://www.p-s-t.com/s.nl/it.A/id.2315/.f?sc=12 I wasnt sure if there was any other suggestions out there.
