Does anyone know the size of the 3 nuts that connect the RB muffler to the RB center section? I tried looking at 81-83 manuals, since they are designed the same, but there arn't any really. I want to buy them from Kragen tomorrow and don't want to make 2 or more trips because I bought the wrong size the 1st time. This is a quick question and basically need just 1 answer. Thanks.

 

Go to OSH instead. They have lots of metrics if needed.

 

I just started to work at Kragen so might as well get the 20% discount off of the $2 set... right...? but anyways.. do you know the size of it?

 

I think it's 9/16" or 14mm med thread.

 

Pineapple racing (.com) sells special copper-based anti-seize nuts specifically for RX exhaust systems for about .50 cents each. Bought a set for my RB system-

It's 14MM. Just played with my exhaust the other day.
