Hi All,

I wanted to share this very small post, if it helps out one person then that makes it all worth it. This is how I removed the rear quarter windows from my R33 today.

  • Remove inside plastics as in the photo
  • Seat Belt will also need to be un-bolted at the top of the pillar only.
  • Rear upper plastics - leave the seat belt and just un-clip them and sit them along the back seat
  • Quarter Trims I also left them connected to the seat belt and just pulled the seat belt out so I could also sit them on the back seat.

  • With the material needed to cut the urethane/window sealant - I used a piece of 0.9mm mig wire - roughly 600mm long, you can use guitar strings or something that is strong enough with a coarse edge to help cut the sealant - but be careful if you need to preserve your paint - I didnt mark any of the paint work today with the smooth Mig Wire
  • Next start by pushing the mig wire into the urethane at bottom corner as in the image
  • When you have is started into the urethane - get a pair of pointy or flat pliers and push the wire through with them, so the wire doesnt bend I pushed roughly 5mm at a time - which provides some form of strength in the wire and doesnt allow it to bend.
  • When you have the wire through - you want to pull it through until it is basically half of the length of the wire - this will allow enough material on both ends to connect the special handles.

  • Next find something that you can connect as handles - can be dowel like broom handle, anything you can twirl the wire and have good hand grip. I used 2 rubber handled screw drivers - see in image this was after I removed one window.

  • Now you have the wire through and 2 secure handles to hold on to you need to start by holding both by cutting the urethane in the direction you want, I started by going upwards first, from bottom to top corner.
  • Its very important to always have pressure pushing away from the window towards the inside of the vehicle - you dont want to be cutting and have the pressure against the window - or you could potentially break it.
  • In some spots I also got caught up slightly on the inner sheet metal tabs - easily averted by changing the direction of the cut slightly
  • There are also 2 plastic tabs, one is a locating tab and another is a clip with locking tabs - but the wont be a problem because this is the corner you should finish at.
  • See in image below - I cut from bottom to top, then I cut from top to the back of the car, then I brought the wire all the way back around and cut from the bottom to the back of the car finishing at the plastic clip - use a small flat screwdriver to help move the mould out a bit to get the wire behind it for cutting towards the back of the car.
  • When you get this far inside the vehicle you can press the clip together to release the pressure - I also used a knife for the last bit of urethane near the clip - maybe didnt need to use the knife but I didnt want to pull on the last bit of urethane and break the corner of the window.
  • See in image - directions marked 1,2,3

  • And thats all there is to it - remove old urethane on glass and vehicle, clean with wax and grease remover to ensure a good clean seal, apply new urethane and refit the glass with the locating lug and plastic clip. You will know if you dont have enough urethane applied when refitting you should have some slightly press out when it seals, too much and it will be harder to press into place and you will have excess amounts oozing out.
  • Up to you but you can smooth out with detergent or cut excess of with a blade when it is dry.
