Exhaust is blowing on the n/s exhaust manifold connection to the down pipe. Tried doing the nuts up and they are just spinning. I was wondering whether anyone has a spare kicking about? Would be loverly if somone had an entire stainless/sports system but i think thats being optimistic

1985 RRC 3.5 v8 on carbs

Would it not be easier just to put new studs and nut on it.
