What are the differences in these 914's besides the motors? Is the frame of the car any different? I am guessing the springs and shocks and struts are different....but is there anything else?

Thank you.

The suspensions are a little different. Same design, different components. The front is now 911T, the rear has 5 bolt parts that are sometimes unique to the car. Body is mostly the same except for the engine mounts. Tranny is similar, but different gearing and shift mechanism. Interior is a little different, but only in detail. For 70 and 71 the steering column and ignition is like the 911. So, lots of little differences, but basically the same design.
