I found an early 80's 320i in a junkyard, from this forum I see that the door brakes can be altered to fit E9's and possibly the shifter can be used to make a short-throw shift mod. Are there any other parts from E21's that can be used (altered or otherwise) for our cars? I am going after the above parts and want to yank anything else applicable while there due to the scarcity and high cost of E9-specific parts. thanks.
