The linkage is made up of 4 pieces. 1) Shift lever on side of trans, 2) A rod going from the shift lever to a 3)pivot bolted the the frame rail just at the base of the firewall. 4) There is a rod going from the pivot to the lever on the steering column inside the engine compartment.
I have everything you need to connect the transmission to the steering column if you want it. I installed an aftermarket shifter and it did away with the linkage and I bypassed the factory neutral safety and reverse light switch and wired in the ones on the aftermarket shifter.
