Console (new from Rares).
Console brackets (from Rares).
T-bar from a HQ-WB with trimatic (just make sure you get a rhight hand shift one) with shift rod attached.
T-bar harness HJ-WB, will plug straight into your harness.
Selector plate for side of the trimatic.

Just unbolt the pull rod from the column (1 x nut/screw) and the twist mechanism off the chassis rail (2 or 3 x bolts).
The nut on the selector shaft of the trimatic will undo and pull off the C-shaped twist thingy, and put on the selector plate for the T-bar.

In theory you should buy a floor shift column and fasica and remove the selector indicator off the dash but you can leave it there if you like.

Plus replace the bench seat with buckets if it has a bench. If it has buckets it will have a seat separator, and you leave the rear brackst for it just remove the front one, and then you just need the front bracket for the console (it will use the seat separator's rear bracket).
