electric mirror

my drivers side electric and heated mirror is broken. the plastic fittings that hold the lens in the housing have broken does anyone know if i can just buy the glass bit or do i need a whole new mirror including housing?
thanks

Hi
Ive just put one on Dads..
The plastic "mount" that joins the mirror to the electric mechanism..was about £4 on net and about £5 from LR .Slides on the back of the glass and pushes on the motor mechanism (Providing you still have the broken glass to fit back!) If so,i went for a stick on mirror Sticks over broken glass,and heater still works through it) for £18 off net...About £15 in Halfords but 2 week wait!!!!..
If your glass has gone,a new glass is £40 out of LR if i remember right..
Hope sum help..
Cheers LTel

LTel, thanks a million. you've saved me a bunch of cash. i thought i was looking at a whole new mirror. i got the plastic piece from landrover yesterday. £2.40 inc. VAT. Fitted in minutes, electric mirror as good as new.
nice one mate!
