I did a write-up awhile back and you may find it by doing a search.
At any rate, the important thing to remember is to be PATIENT, for best results.
Also, I found it to be slightly easier on the late interior console. The early plastic frame at the base has tabs that tend to crack more easily.
You basically remove this frame by prying it gently. It also helps to remove the ashtray assembly for easier access from below.
With the ring out, you need to pull the inner rubber boot upwards and expose the e-clip that holds the rubber **** to the shift lever. Pry that out and put it in a safe place.
Remove the shift **** assembly and gently tear off the leather boot. The shift pattern cap should pop out, but you may need to help it out by prying at it from underneath the leather so as not to scratch it. Be careful not to crack the plastic prongs that hold it in.
Once you have the bare shift ****, you need to drop it through the opening in the shift boot and slowly pull the boot upwards to cover the **** end. It helps to rub some talcum powder over the exposed shift **** before fitting the new boot. As you pull the leather upwards keep pressing it to adapt it to the shift pattern opening in the ****.
As the new boot adapts to the shift **** shape, keep pressing the edges inwards to eliminate the wrinkles. Add a dab of glue to the inside of the edges to hold them in the opening and trim them as necessary for the cap to fit back in. As soon as it looks satisfactory, take the plunge and pop the shift pattern cap back in.
Reattach the shift **** to the shift lever and be sure to pop the e-clip back in.
At this point you can put some rubber cement between the shift **** shaft and the leather for a more professional finish.
Finally, surround the plastic base ring with the new shift boot and pop it back in.
Also, be really careful with the shift pattern cap. The tabs on the bottom break off really easy. I did a replacement aftermarket cap from a company in Germany called cup-sport when I did my shift boot. They've got great metal machined caps & they can laser etch anything you want on it. Say you want porsche badge or turbo logo or even your initials instead of the standard shift pattern. I opted for the shift pattern & love it. I'm at work right now but I can PM you the link tonight if you would like to check it out.
Sorry, its early & I missed the whole auto part. Plus now that I think of it, it gets really hot in the Iowa sun. I can imagine that if you accidentally grabbed it in the Dubai sun after sitting all day, you could potentially brand a porsche emblem or shift pattern into the palm of your hand.
