^Exactly, I was almost to the point of replacing synchros due to the inability of engaging 2nd during high rpm launches at the dragstrip. It was very frustating, I was not able to gate 2nd due to a spongy resistance, going back to stock fixed the issue.
Loosen the driveshaft 14mm bolts next the rear mount, this will allow for room to remove the mount. When replacing the mount back to stock use white lithium "grease", not spray.
