AMC Shorty Headers From Pertronics

what was decided on fitment ? same as the old ones?  small bodied cars this time?

Great! Lots of people call up looking for shorties.

Will they fit a Spirit?

Edel made 2 different sets, Jeep & Car and IIRC 2 with in each set, air tube and non-air tube. When the work went out Edel stopped selling them all you could get where the Jeep ones and was told they did not fit cars.   Or am I all wrong on that and hope the set of shorty headers I have that I think are for the Jeep will fit my Javelin?

As you know 71-up AMC big body cars and the Jeeps with AMC V8's both used "free flow" exhaust manifolds. The Edelbrock shorty headers were designed as a direct bolt on replacement for those cars and the Jeeps with the OE "free flow" manifolds. The Edelbrock shorty headers will also fit the earlier big body cars (if you have dog leg heads) like 68-70 Javelins, AMX,s, Rebel, Etc, but are not a direct bolt on for these cars (that came with OE log manifolds) due to collector location, but (like the "free flow" manifolds) they do fit the engine compartment nicely. The Edelbrock shorty headers will not work on the small body cars (Americans, Hornet, Gremlin) without some major modifications.

So Dave, if the headers that you have are #65812,65813,65912,65913 they will fit your Javelins with just new down pipes if you are replacing the OE log manifolds. They will not fit your Gremlins without some major work.

I hope that helps!

That will be great to get the right side header to fit the small body cars Dan!
