4 spd conv. parts
I know this topic has come up before and I searched old threads but could not find a list of parts needed to do a factory auto to 4 spd conversion on a 71 442.
Here are the obvious things I know of besides drilling crank and adding a bearing. If anyone could add to list feel free.
Bell housing/bolts
flywheel/pressure plate/bolts
throwout bearing
clutch fork
Z-bar
engine mount?
trans
trans linkage
shifter
floor hump
pedal assembly
trans mount
Do I need a std steering column?
Do I need a new crossmember or do I just move the auto?
Do I need a new drive shaft
What about reverse lights?
neutral safety switch?
Speedometer cable?
Any little things that anybody can add? (wires, jumpers, clips etc...)
Thanks

You will also need to have a 4 speed crank that is drilled for a pilot bearing, or drill an automatic crank for a conversion bearing. I bought my conversion bearing from Supercars Unlimited.
The wiring is simple for the clutch switch and the back up lights.
The console harness from an automatic car can be used in the manual trans console.
There are 2 push in sheet metal nuts that are used on the base of the steering column to hold the back up light switch. My auto column did not have them.

Clips for shift rods - 12338114 Also used on the reverse rods too
