The secret to removing the lenses from the assemblies without breaking them is as follows:
1. Use a HAIR DRYER to heat the contour of the lenses where they latch together and also all around where they make contact with the rear assembly. This is to make sure the butyl that seals the lenses to the assembly gets hot and soft. (Hot to the touch NOT BURNING HOT) (DO NOT USE HEAT GUN WAY TOO HOT )
2. You will notice there are V shaped latches with plastic hooks inside, on the top and bottom of the lenses that hold everything together ... DO NOT PRY UP THESE LATCHES with a screwdriver !!!! You must slide a piece of plastic about the thickness of a credit card in between the latch and the hook so that the hook releases. (See Pic Below) Once you've inserted all the cards and the hooks have released reheat the contour a little more ....gently pull apart the two making sure all your latches are unhooked. You will see the lenses will spread and open...
3. Once apart let the butyl cool.... it is easier to clean up and remove the old when cold. You can put new sealant butyl that can be bought in any good automotive shop... the strip maybe thicker but you can stretch it thinner to fit in the slot and reseal the lenses.....
Take you time and be CAREFUL these lenses are VERY VERY BRITTLE
Have fun
