billy failed on the innersill near leaf spring mounting(needs some welding).apparently there are some air con pipes in the way and they may have to remove them.dose this sound right or are they something to do with the cooling system as im worried they dont know that much about bongos.someone please put my mind at rest. 
.i suppose its not a bad mot for a 16 year old bongo.
so job done easily.all done for another year.big relief.
