Do you have an early Land Cruiser and want power brakes? Then this is the part you need. Early Land Cruisers (58-7/70) have a three bolt manual brake system. There are a couple of ways you can make power brakes, all are difficult except this one. This adapter clears your firewall rib and is the proper length for a 79-83 Mini Truck booster. This allows you to have a dual circuit master. Comes unpainted.
