'46 Super Deluxe Sedan Coupe Rear Spring

[51woodie]

After 80 years, the rear spring has lost its spring. I purchased a new spring from Eaton Detroit Spring, P/N ML 659. I will be replacing the shackles and bushings as well, and that is where the question comes up. I haven't removed the old spring from the car yet, to confirm the existing eye spring diameter or existing bushing sizes.
From the Green Bible, if I read it right, the spring bushing is P/N 21A-5719-B, with an OD of 1-5/8", but the new spring eye is 1-1/8"
I called Eaton, and the Rep. called back after checking their "original" drawings, to confirm that the 1-1/8" eye is correct.
The Rep. gave me a P/N of the bushings they sell, HB 862 which measures; .0625" ID X 1.125" X 1.500" OAL.
I'm good with the Eaton bushings OD and OAL, but is the ID the correct size? Suggestions on shackle pins and bushings #' is appreciated.

Here is a NORS set. I’m getting ready to put on an early 47. Diameter are three-quarter inch on the top and one and 1/8 at the bottom.

51woodie, the green book shows 21A-5719-B 1 5/8" LONG not OD.

Thank you Ralph and Bob.

Shackle pins are 5/8" so their bushings should work. The overall length of a pair is a 1/4" shorter than a stock pair; but I suspect they are urethane and don't squish as much (if any) when the shackle plates bottom out on the pin. Guess if there was a little slack a washer on either side would take care of it.
