[Daves55Sedan]

The large red mount bolts directly to the timing chain cover. At the very front of the mount there is a metal spacer that straddles the two bolts that go through the red mount. That spacer sits on a rubber rectangular block. That rubber block sits on the bracket on the backside of the frame front crossmember. There is an identical rubber block and retainer plate under the crossmember bracket.
The large red mount itself is not adjustable. The front steady rest components are adjustable vertically and horizontally.
Assemble the steady rest components loosely until the mount at the transmission tail housing is bolted down tight, then tighten the two side bolts at the steady rest and finally tighten the steady rest center bolt from underneath.
