okay. i just did this.
i learnt through trial and error on the first door, and some scratched tint on my wondows, that will have to be repaired.
anyway. imo. best way to tackle it is to actually remove the pins. allows you crush the the plast surround inwards using a set of needle nose pliers. pull. dont be gentle. you ar going to lose it anyway. the plastic surround is going to be a right off.
as for the new surround. my one were not fully threaded. thead ended about 3 mm to the top. so i did see the point in destroying them using pliers to screw them in.
anyway. my way. a piece of felt. a hammer. felt over new chrome surround. tap. tap. bash. goes right in. it has some movement. use a syringe and push some sicaflex in there. problem solved. takes 4 mins. saves the chrome piece from damage.
I also put the chrome door pins in. looks great.
and yes. righty tighty. lefty loosey.
