Your problem is clutch adjustment. Your clutch is not fully releasing and is causing you syncros to drag. Do not drive it or try to force it into gear, you will break a shift fork and you are also dragging/wearing your syncros out quickly!

Shimming your pivot ball is not for adjustment, its to make sure the end of the clutch fork has enough travel to release the clutch before it makes contact with the bellhousing. It may be your problem, hopefully not. Make sure the fork is at least in the middle of the hole or towards the engine when released.
