More exhaust manifolds

For the driver's side you need the 53006619 360 DAKOTA casting number for the passenger side it should be 53009376. Those are positively the large hole manifolds but not as large as the ones I sell. The way your car is set-up (motor, trans, shifter and manual steering) is the most desirable set up for the large manifolds. If you buy back (or get) the ones your friend has they won't flow as much as the ones I sell but it's strictly up to you???FYI - NO factory manifold was 2 1/4" exit hole EXCEPT the 340, all others must be properly machined to get them out to the size of the 340.
Also there are many, many 360 magnum manifolds out there...the vast majority ARE NOT the large hole manifold. I know which ones are and are not large hole, but none are 2 1/4".
