I reached behind the top of the armrest and grabbed the edge and lifted it up to release the tabs from the slots while carefully pull forward.

I have no experience with upholstering. So, there may be better ways to go about this. You may also want to take the armrests to a professional and have them install the Redline leather covers. Should be a quick job for someone that knows what they are doing.

I used 3M 90 High Strength Spray Adhesive. I left the factory vinyl in place and sprayed a coating of 3M 90 on it. I also sprayed the inside of the leather covers. Unfortunately, some spray got onto the front surface of one cover. After it was on the armrest I was able to remove it by rubbing with a paper towel and then a brush. It may have been better to try before it dried. One person told me they were able to remove 3M 90 from their armrests with denatured alcohol. Best to try it in a hidden area before using it.

The trick was to make sure the stitching seam is properly aligned in the front end and back end. I placed the back end down in position and made sure the front end lined up. Then worked from the back forward, pressing it down with my fingers.

Once the front surface was down and smoothed, I wrapped the remaining around the edges and glued it down.

When it was dry I trimmed the leather back to the edge of the vinyl underneath. There is a groove in the plastic that helps. So, none of the old vinyl showed.

The Redline leather is fairly thick. So, I carefully skived it down on the inside of the armrest with a large box cutter knife I sharpened to razor sharp. Skiving was necessary for the armrest to fit back on the structure -- especially where the leather bunches up at the ends.

To replace the armrests I hooked the bottom on the tabs and pulled up to get the top over the top tabs. With some effort, it snapped into place.
