I'm in the process of building a 75 chassis with a 78 3.0 engine should be fun

. When looking at 914s or any car of the pre-galvanized metal era cars you have to look for rust. The area under the battery is called the "hell hole" for a reason

Also the longitudanals are prone to rust. If you find a clean chassis they are a great platform for a hot rod/autocross machine they just need more power.
