Hello. The steering coupler on my 74 Challenger doesn't look right. With the steering the way it is, really feels loose, I was thinking of upgrading the steering box to a Borgeson. Has anyone used Borgeson power steering box? Thoughts? In the meantime, the picture shows the existing steering coupler. Its missing the end cap. Not sure whats pouring out of the coupler. Would this be safe to drive to my mechanic? Thanks for your help.
