I have an f reg 325i convertible

I bought my car a few years ago. Rarely driven I last few years. Bought to do up as a project. The car is a f reg 325i convertible. Always had issue with rev counter. It used to idle on 0. Now it doesn't work at all. Been told a few days that my car is pre facelift and clocks are from a facelift mod...

Hi all. I'm Akiff. Bought my e30 around 3 years ago. Still trying to restore it slowly, very slowly. Lol. Will try to attach a few pics. Need help with a few bits so sorry for all the questions I will throw at you guys.
