Nut size for 87 catalytic converter
I just went to put the exhaust on the RX7 I just bought and it is missing the nuts for the cat. Does anyone know what size and thread they are? Thanks for your time.

If you use the hardware store ones on the downpipe and near the cat you may have a clearance problem. They are M12x1.25 from the factory but they have extra small heads on them, being 17mm instead of 19mm.
