Help diagnosing clutch problem

[89ST]

Another thought,

Not saying you don't know what burning rubber smells like. but if your hand brake line got ceased and or one your rear calipers is ceased that would make up for the scrapping metallic noise you hear, and the burning smell. Also when you shift and the engine noise momentarily decreases you can once again hear the scrapping noise of the stuck break until you're back on the throttle.
