The rows are the size of the oil cooler. They seem to mostly be 19, 25 and 34 rows. You make the blockoff plate yourself. If the oil won't get warm enough, make a plate to cover part of the oil cooler in the winter.
Make sure you get one with a thermostatic sandwich plate, or the oil will never get up to temp.
