Lookie what $5000 buys you....

On another note, I'm using this car as a test mule for a rear shoulder belt project.

Rear shoulder belts in a 1970 Charger

I'm also planning on installing rear shoulder belts in my red car, Ginger.

The seat belts will replace the lap belts in the left and right rear seat passengers but not the center. Those will remain stock.
@CoronetDarter is also installing shoulder belts in his 69 Coronet.

The Polara axle has been stripped down and the perches are now 44" apart to fit in Jigsaw....

I was 1/16" off from left to right.

6 5/16" to the backing plate on the left, 6 3/8" on the right. (Don't tell the car show judges)

I may look for some used tires to put on these wheels just to have something to roll on. The RF 15" tire on the car now drains flat in 3 days.
The front wheels are 16 x 7 and measure 1/2" further inboard and outboard of the 15 x 6 wheels I have on the car now. The 16s clear by a mile.
These 16s are custom from Stockton Wheel around 2017 or thereabouts. I know, they are an odd size and quite heavy but I don't see them at risk of bending, that is for sure.

One thing you might want to consider... Sometimes having the axle perfectly centered over the springs doesn't mean they are perfectly centered in the car... I prefer to have the tires/wheels bolted to the axle, the perches set on the locator pins & the housing cradled in the perches... Now center the tires in the wheel wells as best you can.. The springs may or may not be perfectly positioned side to side but you can center the tires as well as possible....

Stuff gets welded but it can be cut off and moved a bit too.
I may swap axles tomorrow. Maybe I'll trial fit the huge rear tires to see how the clearance is.
The 68-70 Chargers have wide hips and a lot of body overhang at the rear tires.

Those wheels are 15 x 7 with an unknown amount of back spacing. I always thought that the stock width rear tires in the Chargers and Dusters look way too tucked in. I like a tire and wheel pushed out as wide as it can go.
