Can’t speak of the mid plate and front plate but mad dog made me a nice set for my 69 bird . Basically the same as a Doug’s header back on the day. There was an interference w the upper a arm but I sent him
Pictures and I think he’s probably made the needed changes for that now. I just had to dimple mine in that area . But you hav to jack the engine up considerably to get that header out that’s for sure. I’d say it’s either that or custom on the car

Pretty sure Custom will be needed to be built on the car.The only sure way to have them fit.I think Maddog got rid of the jig for V headers.They used to make them for Nunzi.Tom

Info for ya.
Ideally the tubes should step up in ID whenever there’s a bend of 45 degrees or more.

Just heard back from S & W and they don't do headers.
Anyone know in the Pennsylvania / NJ area that may be able build custom RAV headers if I trailered the car to them??? |

Seen a thread on another site looking for a header builder. They recommended Farks Supercars in Keyport NJ. Good luck.

I thought DCI was producing headers? http://www.dcimotorsports.com/produc...ir-five-parts/
Or maybe it was McCarty racing? I swear I remember seeing a big bin full of finished RAV headers somewhere online.
