So my MCSS junkyard steering box has developed a problem, excessive play from a left to right to left transition. I found an 1986 Gran Prix in a local salvage yard, factory gauges, buckets, 305 sbc, 200r4, F+R swaybars. I assumed it would have a fast ratio steering box, so I grabbed it. Appears to be 3 turns lock to lock, found a DM stamp on the end cap. Any idea how to determine what ratio it is? I've searched here and the interweb with no results.
