I'll be replacing a muffler and tailpipe this weekend on the '82 Westy.
Picked up the parts, but as is usual with me, I realzie what I DON'T know
only after I've left the parts shop.  The muffler and pipe are by ANSA.  I
picked up the gasket that goes between muffler and pipe but, and here's the
first question:
1.  Does anyone know what size and thread are the bolts that hold the two
parts together?

I also picked up a new clamp for the catalytic-muffler connection, and
here's the second question:

2.  Is there a gasket that belongs at this joint, or is it just pipe to
pipe?

And, since this list is so helpful, any other hints and tips for exhaust
repair?d
