Greetings, I have a few questions concerning checking out a Junior. It is a 1968. The owner doesn't seem to be able to answer very much. Are all the Alfa parts easily interchangeable from the 1750 and 2000 to make a higher performance version? Items SUch as brakes, engines, rear ends, etc. I am not very knowledgeable when it comes to looking at an Alfa. Will of course look for corrosion above all else. The car was said to be running well when it was last run in 2007. If there was one area to concentrate on while looking for rust, what would that be? In this preliminary check I will have no access to a lift, just crawling around on the ground with a light, screwdriver and magnet. . Thanks in Advance.
