Magnum exhaust manifolds

[roughcut]

New guy looking for details about 383, 440 Magnum/Commando exhaust manifolds. Obviously, the shape but what's the difference between cast/part numbers for E bodies vs. other bodies (A,B,C). Also, do the repops match the quality of originals? Probably an exhaustive  subject, but if you could point me in the right direction, I'd be appreciative.

All HP B/ RB engines shared the same manifolds in the same year & body style .
In different years the flanges chaanged but TTI can match to any manifold if you give them the Casting #s if you are not concerned about the year , mostly the bolt position was clocked differently .
A body manifolds are very unique just the fit around steering etc , C body are also very different again due to different positioning .
B & E body manifolds are the same as Ebody as the ebody mostly shares the B body engine fitment .

Thank you!
