Looking forward to talking with you.Thank you,Vedat 

Thank you for getting back to me.
The pivot bars are seized. Don't know how to take them out unless there is a tool for it. This is my main concern at this moment.
I will try to get the pivot shoe out by cutting the plastic as show on the video. I will then be able to send you the photo and exact dimensions.
I took one of the balances off. I will be able to measure and send you exact measurement.
