Hi Albert!
A rusty 914 can give you a lot of great parts and let's face it, there's no beating the price. When we built our kit Thunder Ranch 550A-6, we wound up using alot of 911 and 914 parts. Depending on which suspension setup you could use, steering, front suspension, brakes, master cylinder and pedal assembly, engine, transmission and shift linkage. We also used hubs for 911 5-bolt and 911 wheels. I saw a really nice spyder down at knott's with a set of 914 gas-burner wheels there were polished. Alot of people dislike the Mahle gas-burner style wheels but these quite looked nice and were different enough to garner my attention.
We used 914 transaxle, side-shifter and all of the linkage including the portion that places the shift-lever in the car. The linkage is mechanical so shortening it was relatively easy. All the parts work and the bushings are stock 914.
If you are using a rack-n-pinion on your kit, look hard at your 914 setup as you may find that the steering column will also work for you, especially the universal joints. To use a center pinion rack like your 914, you will have to use double-universal joints. Scavenge them from your donor or pay dearly.
have fun building. angela
