Hi Doug sure.
GE isn't very big in the UK lol.
But espares can sell you one that will work if you give them the size.
The best place to order a new glass turntable plate is: espares.com
I would call them to order this part, if you call also you can get same day shipping on this one !
Please contact them:0844 9777 888 .
In any case, I will stick with you until this is complete.
Please rate my service kindly.
Also it is the only way I am credited for my time and expertise with you.
Once you rate, I will be notified and will add your question to my priority list so you can reach me anytime until this problem is solved.
Then you can reach me by simply replying to this message anytime.
Thank you Douglas.
