I just did this on an MD2020 yesterday.
For Volvo I used the part mentioned above from Ebay (LCD replacement from China labeled VDO/Kenworth/Penta odometer) and used this video as instructions. The tach part took about 30 mins being very careful and it works great! Getting access to the back of the instrument panel was about 10x harder than taking the tach apart and replacing the lcd.
