[240Z Horn Button Refab]

I could use a plastic horn ring as well......has Phar gone MIA?

[240Z muffler dimensions]

I posted this in the L6 forum but have not gotten a response so I am reposting here.

Can someone post the dimensions for the OEM 240Z resonator and muffler.

Making a custom exhaust and it would help if I had these specs.  The factory parts manual

seems to show the forward resonator as oval and the rear muffler as round?  most

of the aftermarket systems offer an oval rear muffler?  Any input is appreciated.

Can someone post the factory OEM dimensions for both the center resonator and the rear muffler. 

Were both mufflers originally round?  Most of the aftermarket systems show an  oval rear muffler.
