I do have everything from flywheel to drive shaft but it would be very expensive.
If you try to buy pieces it will take forever to find them.
The pedal assemblies are different for manual brakes and power also.
A rough list:
Roller bearing pilot bushing in crankshaft.
Flywheel
Clutch disc
Pressure plate
Throw out bearing
Clutch fork
Adjusting rod
Tension spring for adjusting rod
Z-Bar with bushings
Z-Bar pivot bracket on chassis
Z-Bar pivot bracket for Bell housing
Clutch pedal to Z bar rod
Clutch Brake pedal assembly
Transmission cross member, Some auto are same as manual.
Transmission rubber mount
Top Loader Transmission, Dan Williams will rebuild for $350 + parts but shipping is a killer.

Shifter, 71 had a flat shifter 72 73 round
Shifter boot very difficult to find good for flat shifter
Some early cars had a rubber boot cover on the shifter under floor
Plastic shifter boot trim goes under console
Drive shaft
Might need speedometer gear change not sure?
Did not list bolts you can make do if you do not have.
So that is quite a shopping list to go find individual pieces. As someone stated a good rusty parts car is your best bet or keep and eye out on the insurance sites for crashed cars.
I doubt that $3,000 would by my complete set up.
Going with 5 speed is for sure easier in some ways but also not just a cheap solution.
Good luck and welcome to the forum.
