[80euro635]

I recently acquired a 1980 EURO 635CSI, that has been in garaged for the last 10 years. Where I'm having issues is locating the correct parts. None of the websites I go to give the option for a '80 635, all the websites have for 1980 is the 633. This doesn't help when I have the 635. What I'm looking for right now is a passenger side window, injectors, and valve adjustment specs. If anyone has any information PLEASE HELP!!!
