Just gone and bought my very first series 2 escort rs turbo

Its been brilliant and been having some great fun. However went out side this morning to find a massive patch of what looks like gearbox oil.

After further inspection it has filled the under tray beneath the gear box with oil and is just dripping out the water holes.

I can not see any leaks from the top of the box and by the looks of things I dont think the drive shaft seals have gone.

Cant seem to get the under tray off eaither as 2 of the studs just turn and cant get another spanner on the other side

Please help
