Shift Linkage
When you turn the Porsche 930 transaxle around for mid-engine use, your shift mechanism is now at the very back of the car. The problem is usually solved by cable shifters. They are expensive, so I tried to build a solid shift rod mechanism based on the Jamar shift linkage used on mid-engine VW sand rails. The Porsche has really tight gates, so it was hard to get the long mechanical linkage to have the right sensitivity for precise shifting. I decided to bite the bullet and order a cable shifter. That created another problem, requiring me to re-design my rear transaxle mounts to make room for the cable shifter cables. Like many things in a project like this, you can end up re-doing something two or three times. Fortunately, you generally end up with a simpler and more effective solution.
