Viking VAMBK Next Generation Motor Brush (Single)

We need motor brushes for the Viking F1 Viking slide gate. Parts say it is the VAMBK but the motor brush you offer at your site shows a different picture. Contacts at the end are round where they are square on the original part. I cannot find the size of the carbon square for the VAMBK so the question is will you part for the motor brushes that you show on your website fit the Viking F1 swing gate?
