the right crank arm from 84 is no longer made , anymore .
if the thread repair scheme is not chosen , a whole crankset and BB and starting over is a lower resistance route than trying to find old parts.
after all this time ..
a crank with a similar tooth count installed with the same chainline (right BB to go with it)
would let the old derailleurs continue the shoving the chain sideways , job..
cant help you from a keyboard , but the warm bodies at Bike shops where you live, may .
