Hi Hi_Fi_Guy- Huge fan of Lakewell's kit. Mr. Van der Meer does include DIY instructions, but I opted for a local pro (recommended by the Porsche dealer) for the install. It's been over 4 years and really pleased. It appears he does offer the Pepita inserts as a standard option for his '71 kit.
911 Cooking- The compound butter made the difference.
