I take a steel plate & drill 2 holes in it to fit the coil mounting holes. Then drill a larger hole in the other end. Bolt it to the coil holes with grade 8 bolts & hook one end of the chain to the bracket. Wrap the other end around the rear part of the intake manifold. If the manifold is off use one of the bolt holes. It,s best to leave the trans in or pull it separatly.
