If I remember right, the time you posted this question before you had some of the parts, right? If that's the case, my telling you that it's simpler if you get all the parts at the same time won't do any good. However, match the type. Take the part you have to the parts store and have them order the correct other part. Borg should go only with Borg, etc. I get a lot of parts from a local independent parts store, and it's surprising what these guys know. They're all mechanics and I can get good advice in addition to correct parts. They even have a fair selection of parts for 122s. I don't know why, and they don't either. 'problem is - they recognize who it is when I call about parts for one of the Volvos.

Just a comment. It's worth-while cultivating a friendship with parts guys. I don't have to pay a core charge (can bring the core back when I'm through) and they will commonly press bearings in, etc. at no cost. Donuts and soft drinks to say thanks go a long way with these guys and a "used parts store" I frequent.
Besides, these guys help a lot.
