Re: [Chrysler300] 413 rebuild

[<rfx300l@xxxxxxxxxxxxx>]

Hi All
I have a pair of exhaust manifolds PN 2843992-1 {Left} and PN 2806900{Right} 
They are 2 3/8" openings. www.hobbydigest.com list them as for 1967-1969 
383-440HP. They also show casting #'s for the J and K plus a number for the 
B/RB truck.
