Strange! Luckily one of us was late coming and stopped by a garage and picked up the parts! Turned out the diff blew, all parts delivered for £80 can't complain haha.
Got it running during the night, went out again Sunday.
@The Mad Hat Man Ahh nice! Where were you? I've been a few times but this was the first time we didnt bump into any other groups except for at the very end of the day!
