Batwing side plate for axles that don't have the Ford perch pin boss. Holes are 1/2" diameter on 4-3/4" centers.

The 4-link brackets are 3/16″ steel. The hairpin bracket looks very similar, but has 3/8″ holes and is 3/8″ steel to mount a clevis.

The plate can be trimmed with a hole saw to fit your tube axle, or trimmed by hand to fit an I beam.
