3-2 Line Control Valve and Spacer Plate Matching
85-1/2 and later 440-T4 spacer plates are matched to the 3-2 line control valve.
Refer to the following figures for identification.
One piece valves and matching plates are used with the "small" engines (2.8, 3.0, & 3.1 non-turbo). See figure 1.
Two piece valve line-up and matching plates are used with "large" engines (3.1 turbo, 3.3, 3.8, 4.1, & 4.5) See figure 2.
Spacer plates and valve line-ups are not interchangeable between "small" and "large" engine families. Keep two piece valves and plates with "large" engines, and one piece valves and plates with "small" engines.
