I wouldn't be too worried about the gasket, I'm 90% sure I don't have it on my driveshaft.
I would put a dab of thread locking compound on the side shaft bolts as a bit of security.
My solid diff bushes should be delivered today so I will be rebuilding the car in the next few weeks and will be able to get pictures and measurements for those who require them.
