R32 Gts-T 4Th Gear Synchros?

Hey guys, so i just picked up a GTST this morning.Literally on the way home driving, as I was exiting the freeway I gave it a squirt in 4th and then pressed the clutch again. Was probably at about 5000 rpm. I cant remember correctly if the BANG was before or after i stomped the clutch, but none-the-less there was a bang.The car didn't want to get out of 4th, but was just revving out when accelerated. Came to a stop, and yanked it out of 4th, and drove on.

Basically no 4th gear. All the others are fine, 3rd crunches abit and reverse does too now, but they all go in and drive. 4th will still go in with a crunch and out with a crunch, but its still neutral. Would this be 4th gear synchros that have given up?

Drop the oil and report on the colour of the chunks of metal that come out.
