From Modest Driver to Mopar Dream Car: Building the 1970 Charger R/T 440

This 1970 Dodge Charger 500, 318 under the hood, arrived at Driven Restorations LLC

 October, 2014

✯The Dream✯
This project started as a harmless conversation after we met the owner at an unrelated networking event. We said "classic cars", they said "Plum Crazy 70 Charger" and before you could say "R/T" the wheels were spinning and a build plan was in the works.

It took months to locate a '70 Charger within a day's drive of WI, needless to say there weren't very many Plum Crazy 440-6 Mopar's on the market. So when the owner's found a Charger in Arkansas, they moved quickly to get their shot at starting a MAJOR Mopar transformation. 


How major? 


The highlights include 318c.i. to 440 6-pack. Column shift to floor shift. Bare interior with a cargo seat to an original interior with Leather bucket seats. Flat black 500 SE to Plum Crazy R/T package.

In anticipation of the car's future form and anxious to get behind the wheel, the owner got the brakes working enough to trust them (most of the time). After a new battery, airing up the leaky tire and replacing a few parts under the hood the 318's carb was tuned to get it running. 

Only one thing was missing... 


custom seat for 1970 Charger
1970 Charger arrived with a custom seat but almost 
all of the interior had been stripped for parts 
A place to sit.

With almost no interior to speak of, this Charger required a little ingenuity before being driven. The owner installed a  "double"seat, removed from a conversion van.  The seat provided just enough room for 2 people to enjoy short drives before the start date for the classic Mopar's major overhaul. And it has since been tranformed into a shop seat...as a memento of the car's former life.




✮Future powerhouse✮

The 440 Mopar arrived along side the car. Purchased from an engine builder by the owner, the freshly re-built 440 will be quite a change from the tired 318. Add the Six Pack, Hooker headers and Dana 60 to the mix...This Mopar will never be the same.

✮Tear Down: The Good, The Bad, The Ugly✮

We often find interesting things when stripping cars. This time around was no exception. There were trinkets hidden in the depths of the cowl (assorted pocket change, hardware and a toy car). The paint colors varied from orange to dark blue, a few areas of red, and of course the flat black that covered most of the car. 
The good news: the structure was mostly solid 
The bad news: there were far more missing parts than we had hoped. Somebody knew what was worth selling off this car and took full advantage of doing so.

While mildly annoying, we wouldn't call the rusted sheet metal and missing parts "ugly" per se...but wait. There's more...

The Ugly: Somebody fancied themselves a sculptor in a past life, and took the liberty to repair(or would it be sculpt?) the one year only, not available aftermarket, NOTORIOUS for rusting out and extremely expensive to replace 1970 Charger fenders. The hack job on these fenders was enough to make us cringe in disgust and would likely bring any Mopar lover to tears. 

1970 Charger Fender repair  1970_charger_fender_bad_patch
A combination of fiberglass, layers of body filler as well as a generous amount of household screen was hiding in the fenders and a couple locations in the quarter panels. 

To add to the fun, a few key structural parts were removed to allow room for the assorted patch materials.

✮Blasting✮
With the car on the rotisserie, it was sent out to our blasting shed and the paint was removed from the majority of the sheet metal. Knowing we would be replacing both quarters and the roof with fresh metal, we didn't waste our time (and the customer's budget) on removing paint or rust where it didn't need to be removed. Overall the body looks about as we anticipated with only one or two areas with hidden surprises in need of repair.

✮Metal work✮ 

Major surgery is in order for the Charger, and there are no short cuts if you're going to do it right. The new sheet metal will be fitted, trimmed, prepped, fitted again, aligned with surrounding panels, trimmed, fitted (again) and then finally welded in place. Some parts are not available in aftermarket stamped metal(especially stamped metal that will fit correctly), so we will be making our own patches where needed.  OEM used panels will replace the missing or too badly damaged parts like the front valance and fender light openings as well.

New, full floor pan, rear cross rail and rear valance are "mocked" into place. They are held secure via screws and clamps to ensure proper fit, spacing, and alignment before being welded.

Outer wheel housings and trunk extensions were also replaced. Shown here is the right side, ready for the new wheel house, then the quarter panel.

Some of the most critical steps to this build are pictured above. If you've heard the saying "measure twice, cut once" you can appreciate the meticulous process of panel replacement, which would more accurately be described as "measure 3,4 or 5 times and trim 1, 2 or 3 times then weld". Each body panel must align properly with the ones next to it. Ensuring proper placement, spacing, and alignment is essential to a #1 restoration and, more importantly, the future functionality of the car. We have a few tricks to accomplish this but if we told you, we'd have to kill you.


1970_charger_trim
Trim inspection and selection
This car arrived with some trim, but not all of it. We needed to take a complete inventory and determine what to re-plate or polish, and what parts to purchase aftermarket. We ended up with 1 complete set of trim and a few extra pieces to re-sell at a later date. We'll be using the trim during panel fit and alignment to check mount locations and proper fit before we weld the panels in place.

charger_bottom_body
The Charger body is still on the rotisserie, which allows us easy access to prep the bottom of the car's body for epoxy primer and seam sealer. We did a lot of metal work, and now we have to protect that metal for decades of enjoyment.

Stripped_ecoat
Quarter panels were stripped of e-coat to ensure proper adhesion of our materials to be applied to the body. There were several imperfections and a few rust spots on the these panels that were quite obvious after stripping the e-coat, which is why, when you want a perfect body, you have to put in the time and remove the factory e-coat.

✮Interior and Trim✮

To start the interior work, we had to locate a set of donor seats and purchase the seat covers and foam. The upholstery work was sent to United Auto Trim to be installed to ensure a perfect fit and finish for the black leather bucket seats.
