I read how other builders routed their shifter cables and there are many different approaches. Jim from CableShift recommended that I route the cables tight to the engine oil pan and away from the exhaust. The cable comes out of the firewall on the right side of the block, so securely clamp the cable tight to that side of the oil pan. Add 1 more clamp where the cable passes under the transaxle to maximize ground clearance and keep it away from the half shaft.
The cable's inner lining is sensitive to heat, so add some heat insulation to protect the cables from the exhaust header. I used 3 layers of heat protection:
- The cables are covered with heat sheathing
- I fabricated an aluminum heat shield
- The headers are wrapped
This routing work keeps the cable as straight as possible and I've had no heat problems.
The shifter bracket and coupler is different depending upon the type of G50 transaxle. I have a G50-20 (long tail case), I that I shortened. The G50-20 has a shift rod in the tail case, while others have a lever on the side.
Event though I shortened the tail case as far as I could without getting into the internal oil journals and shaved the coupler down to 3/4", it was still about a 1/8" too long for fit within the street tail. I ended cutting a chunk out of the body for clearance. Its fortunate that its hidden behind the licence plate.
Note: I went thru 5 prototypes with Jim at CableShift in developing bracket and coupler for the G50-20. My SLC is at the upholsterer, so I posted the PICs I have, which include some prototypes that were close to final. Your production bracket and coupler are a little different.
