A few things you'll need....
3F Radiator
3F Fan shroud
3F radiator hoses
3F frame mounts
3F motor mounts
3F engine brackets
3F rear mount
3F accelerator cable
3F fuel lines (or freshly made)
3F intake
3F air filter lid
Possibly longer high pressure power steering hose. The gearboxes appear to have been moved forward a 1" or so than a 3B, at least.
Possibly new cables. Dunno where the 3F starter is.
The speedo and tach should, being operative, function, but don't know how accurate, since the VMs are 4.56 diffs.
Sure there's more, but just off the top of my head....
