Well went ahead with the Borgeson 800 Series power steering box and coupling (rag joint) upgrade, and the Borgeson 800 unit is now installed in the Fire Am.
The new P/S hoses have arrived, and they are now waiting on the new power steering pump and lower steering column ball bearing upgrade (replacing the OEM plastic bushing); they should both come tomorrow, Friday.
Once that is all in, another new intermediate steering shaft will be installed to complete the upgrade.
The coupling in the new-last-year intermediate steering shaft developed excessive play and was making a clunking noise.
It may have failed prematurely (or may have just been defective) due to the shaft making very slight and intermittent contact with the rear part of the upper control arm due to the increased number of spacers required to get a more positive caster.
The pitman arm will be connected last to permit easy turning of the steering to facilitate installation and alignment of the box, coupling, intermediate shaft, and steering column.
HAPPY THANKSGIVING to all!
