Not a job i wanted to do, was either do it myself or scrap it
Doing it yourself gives you the time to do it properly. If the chip is repairable id repair rather than replace. I chose to replace with non heated version and disconnect the wiring as the scuttle will be off anyway, so i have spares if you break them. Non heated screen is far lighter and much much cheaper than the original.
Bottom trim slid out no problem then got the clips out later, lost my patience with top trim and ripped it off in anger. clips are fragile they dont need to be strong to hold it in. i reused most of them and bonded the bit i buckled back on with the windscreen bond and clamped it overnight.
No leaks or whistling but the trims buckle very easily so gently bently
