| | | | Joined: Jan 2011 Posts: 306 'Bolter | | 'Bolter Joined: Jan 2011 Posts: 306 | i have two sets of manifolds.
i'm sure they are from a 235 or the gmc equivalant.
the intake casting numbers are the same.
the casting numbers on the exhausts are different but the measurements are the same.
i can't find any of the casting numbers in my hollanders.
does it matter?
