Accelerator Spring - Throttle Spring Replacement for P15

[tollertdi]

Need to replace my original Throttle spring for my '48 P15, part number 1120-847.  Does anyone know of a close replacement for this spring?  I taped it together, photographed it and measured it.  

 

All Dimensions in inches:

 

Hooks are 90 degrees apart.

 

Coil diameter:    .565  outer diameter

Coil Length:       1.935

The first picture shows my spring.  The second picture shows my setup from the parts manual.

Take your spring to your local hardware store, they should have something close in stock.  My local True Value has a decent selection of all types of springs.

I believe, Vintage Power Wagons or Andy Berbaum also have them. True Value is also a great suggestion.

If you have the means and are feeling like putting in more work than required, This Old Tony has a great video on making your own springs as well.

Amazon has a Dorman Help! Assortment kit.

why it is referred to as an accelerator spring I have no clue...its function is to prevent acceleration without manual intervention and aids in deceleration.......throttle spring...now that is correct.....getting silly now...heading to the great outdoors to do some yard work...

The spring on my '48 DeSoto is the "second type", which is about 7" or so. I hunted around a bit, and settled on a double spring (spring in a spring, in case one breaks) for a Plymouth 440 Barracuda. Should give me about 15 extra horsepower.
