Re: 73 Plymouth duster question
 

One other thing the Tail Lights must Macth the front end.
The Demon Tail lights are a total difference than any Duster Tail lights.

We went throught this is Super Stock.Had to change from a 1972 Plymouth Duster to a Dodge Demon to stay in the same Class.Change Front ends and Cut tail lights out of the Duster and instal Demon tail lights.

Re: 73 Plymouth duster question
 

If you decide to change the taillights to a Demon and keep the front end, you will be limited to a '71 Demon with a high compression 340 or a '72 Demon with a low compression 340.

Side marker lights are also different between '71 and '72. I don't know how picky tech is with that or with any small differences between a '71 and '72 Demon grille.

The right 340 combo for 1970 340 with the Carter AVS carb,
The right 340 combo for 1971 340 with the Thermo-quad,
Tail-lights are also different on the Dusters,
I would say, 'can' the Demon experiment, and stay with the option on the Duster, for 70 or 71.
As for the 318 2- barrel/230HP rating in the early 70's. A 'Bad' combo
in K/S and later L/S.

Am wondering out loud why they are so fussy about that tail light difference? No wonder car counts are dropping.....:D WJ

Re: 73 Plymouth duster question
 

Its the "LOOK" and integrity of the class. Everyone calls the class cars Bracket racing but they dont need to look like bracket cars.

Re: 73 Plymouth duster question
 

well its going to be a 73 duster I decidied. all I need is a grill front fenders, so no big deal. now I just need to decide if I want to go 340 or 360

Re: 73 Plymouth duster question
 

'73 has to be a 340 only
'74 has to be a 360 only

The main difference between the 2 model year bodies is that a '74 has rear shock absorber-type bumper brackets. Not sure how strict NHRA is about that but NHRA regulars may know. They do help with the weight in the back since they are heavier than standard brackets used in previous years.

Myron,

Now that would be funny, letting the huge aircraft carrier bumper mount slide but worrying about some plastic tailights!

Re: 73 Plymouth duster question
 

Bobby,
Yea, you never know. Some tech guys may pass it and some may not, if they even notice. So it's best to ask.

Re: 73 Plymouth duster question
 

Guys, the difference in the tail lights on a Demon and a Duster is HUGE! It would be like a Camaro running Firebird tail lights! Also the Demon has a one inch longer wheel base than a Duster, 107 to 108. Check the specs. They are both A bodies but there are big differences. Front fenders, hood, grille and bumper (depending on year). I don't think a Firebird would pass tech with Camaro tail lights. Jim
