When I was younger I worked at a salvage yard and 90's ford taurus's automatic transmissions have the exact shaft. It just slips in behind the torque converter. A core transmission donated it to me.
It is a stand alone 3 wire harness that plugs into the neutral safety switch on the driver side of the transmission, then (on my 1973 Barracuda) runs over the bellhousing to the passenger side, then up the firewall and into the wire loom holders on the firewall and if I remember correctly...
I had steel core my dash pad redone by YearOne in 2024. The cost then was ~$1200 with free return shipping. I see the price has gone up to ~$1300 and return shipping is not free. The Year One dash is not as nice as a Just Dashes pad but my dash looks great compared to the large cracks that I had...

My 73 did not have any bearing at the end just a foam seal to help keep dust dirt and wind from coming up into the column. The steering box will hold the shaft in the correct location.
I have the same brakes on my Barracuda but drilled and slotted rotors. The car stops great, very hapy with the disc brakes. Did you also buy the proportioning valve from the donor vehicle?
I had another 73 barracuda that was drag raced and had the same "kink" in that spot but only on the passenger side. On my car, I think it was from drag racing.

My 73 used the top picture. Three bolts and metal clips that are mounted to the lower valance out of sight below the grille and the two screws on each end with metal clips.
