Ok, so managed to find time to swap over the brackets, pretty much made zero difference!
So....is the issue with 5th gear maybe related to me having to ram it in to gear without a clutch when travelling home from Knockhill last time?
Symptoms:
When low revs, 5th gear engages without issue, high revs in to 5th gear gives a crunch (like if the clutch wasn't fully engaged)
This happens ONLY in high revs and ONLY with 5th gear, all other gears engage perfectly no matter how high I rev it.
Point to note, if I am high revs in 2nd or 3rd gear, it still does it, not just from 4th to 5th, so speed is not a factor, only revs.
