Another 'what size are my nuts?' thread.
Exhaust replacement beckons but not until next week when it arrives. Truck is 1999 C2500 Suburban 5.7l and has dual cats that then join to twin pipes (resonator?) which lead to a single muffler (dual inlets, single outlet) which I believe is what it would have left the factory with.
The connection between the cats and twin pipe (resonator?) is secured with three nuts. What size are they? They will likely need replacing and if metric I probably have lying around but not so if imperial - they'll need to be ordered. Metric or imperial and what size?
TIA.
