I am investigating the possibility of changing the nose section of my '84 Dodge Rampage to be an '83 Dodge Rampage.

Apart from the front nose section and hood, there are no other differences between a mid-year '83 Rampage and an '84 Rampage.

Are there any rulebook / logbook implications associated with declaring a change of model year for any particular vehicle?  I know it's been done on other vehicles, but I'd like to sort out any potential roadblocks before going too far down the path.

The reason I'm considering this change is that for the "Single headlight" front ends of an '83 Rampage, there are factory headlight covers which are rare, but available.  For the quad-headlight front end of the '84, I have been searching for 4 or 5 years for an ultra-ultra-ultra rare set of factory headlight covers.  The underlying question is whether the '83 front end with headlight covers is more aerodynamic than an '84 front end without headlight covers.

My intention would be to test both nose sections at an ECTA Arkansas Mile event, (an '83 with headlight covers versus an '84 without headlight covers) to see if there is a clear advantage to either design.

As always, any help/guidance would be appreciated.

Steve.

Considering all the variables running at a meet present maybe consider instead doing a 'coast-down test'....

Then you wouldn't even have to wait for an event,

I've questioned that myself.  Is yours considered a "production" class?

I don't have an answer, but I can say that some of the variables I've run into with the Midget, being a production based class, and factory production run based requirements, have been -

A switch from 2 to 3 windshield wipers
Split rear bumper to solid one-piece rear bumper
Side marker light location
A one-year production change (1970) from squared off real wheel openings to arched rear wheel openings - and then back to squared off openings for 1971 - God only knows why
A factory switch from a flat-faced grill to a recessed grill then off to federalized "rubber bumpers".

I chose not to fight any of it and stuck with the original bad-aero grill opening, squared-off wheel arches and split bumpers.

At the end of the day, if you're in a production class, I suspect that the worst case scenario if you change out the grill is that you may have to have the car re-registered as an '83 with a new SCTA number and inspection.

I'd make a phone call - SCTA-BNI may not really care, but there are always those who do . . .

Can't 7you make headlight covers that duplicate the factory parts? I believe that exact replicas of factory parts are legal.

I agree with Rich.... find factory literature that shows the covers...  make identical pieces, run your truck. 
We fought that battle in 1979 with the Abarth Zagato.  The car had optional headlight covers that added significant aero to the recessed in the fender headlight.  They were of course unobtainable. We had pictures from factory literature, made identical pieces and ran the car.  It was protested, we did not run the covers the year before.... showed the pictures, protest denied.

Hate to admit my ignorance but I had no idea what an Abarth Zagato was so had to look.



I guess this is without the covers and ...




.... this is with them?  I don't think I ever saw one of these in real life.  Pretty aero looking car, especially the top from the windshield back and down.

Sorry for disrupting the thread  embarassed,

Floyd - yes, those are for the "single" headlight models (up through '83).  Those are very rare, but it's possible to find them if you keep looking hard enough.  The sites who say they have them in stock never do, I've tried them all.

The '84 and up models have quad headlights, with a different set of part #'s (P4286820 for the clear, and P4286821 for the tinted).  They are listed in Direct Connection catalogs from "back in the day", but without photos.

If you can find even a photo of the quad-light covers, I would be very grateful.

Chris:

Diesel Truck defaults to the language of Gas Coupe classes in terms of allowable modifications, as opposed to Production classes.   I don't think there's any functional difference between the two sets of rules as related to body panels, ec.

I've been studying all the part#'s, dealer literature, and any "enthusiast" information I can get my hands on to determine the differences (even subtle ones) between the various years of Dodge Rampage production (there are only 3 years to be concerned with).  In '82 and early '83, there was a slight difference in the fenders where they meet the cowl.  In late '83 and '84, that portion of the fender remains the same.  I can't find any other differences to the sheet metal, trim, or rear bumpers.  The front "nose cones" are different for '84, however.

Here is a quick pic "as run" in 1980 I think.... The young kids... they are older now...
And then back to the question at hand...
