One additional thing worth mentioning.
I had the alternator end nut come undone and the bolt made a break for freedom. I reused a nut and bolt and I guess the nylon lock was passed its best.
The kits now come with new bolts and nuts, so in theory this shouldn't happen to others but I thought it best to highlight it.
I purchased another M10 x 80mm bolt with new nylock nut and added a little threadlock as a double safeguard.
