Gonna take them off tomorrow and attack them with molegrips, heat, and a drill hopefully one of these should do it. It all started wen I jumped the car for first time after rebuilding engine and in all the excitment of it firing up first time and keeping an eye out for any leaks forgot to take off jump leads and also left other motor running then flames from batt neg lead and earth strap unfortunatly the black plastic from burning earth strap decided to sit on the plastic pipe coming from the bottom of resovior.
