Hey everyone! Just a follow up,
It was the input shaft bearing, i tore down the car, replaced it, (with new clutch etc.), and it drives beautifully once again! I wanted to put some decent mileage on it before I confirmed it fixed.
That bearing was completely FUBAR. ive never seen a bearing that messed up. But a new shiny one has taken its place!
But if anyone else has that noise, you know where to look now! haha
Thanks again guys!
