IPD has points and rotors available for your 164 B30E. Lots of stuff like that also available through eBay sellers as others note.

If you're going to own something as old as a 164 then you need to hone your parts searching skills. Parts lookups and verification for old Volvo's can be difficult and you can't trust all the sources to have the correct fitments or even any fitments. If you can pull a number off the part that will sometimes help get you started. Realize that many parts will also have superceding part numbers. Parts lookups by year, model and engine generally don't go back earlier than the 240 series on the genuine Volvo sites and most aftermarket sites -IPD being one of the more notable exceptions. The most reliable place online for fitments and determining your p/n's, also a source for parts in Europe, is Skandix. That will often give you p/n's you can't find elsewhere and a much more accurate guide to fitments. Then you can Google search using the Volvo p/n. That then usually leads you to Bosch p/n's so you can also go searching by that. EBay is Google indexed so most stuff will soon turn up. Every time you do it your searching skills will get better for the next time.
