You can weld these brackets to your 9" Ford housing and install in your GM Metric chassis. Includes upper and lower control arm mounts. Welding required. Designed for 3-1/2" axle tubes, but can be fitted to 3" tubes.
Warning: The top control arm mounts are 'trim-to-fit' because of the differences in 9" Ford housings. The lower mounts are a single hole design (they do not have multiple mount holes.) The also DO NOT have a shock mounting hole.
