Replacement pivot bars and coil balance

Question

I'm looking for replacement pivot bars and coil spring for a house built in 1977. While there doesn't seem to be an exact replacement; I have narrowed it down to 26-021, 26-360, or the 26-444. The pivot bar is 2 1/2 by 5/16 by 3/16 inches. There are two screws but only one goes through the bar at 1 3/8 inches. See attached photos. If this helps, the shoe has patent number 5,704,165.

For the coil spring, it is 1/2 inch wide and appears to have the number 9 stamped on it. See attached photo. The design should be the series 152.

Any help is greatly appreciated.

Looking at your photo, I think the 26-444 is our best bet. Only one screw hole needs to match, which appears to be the case. This part would be my recommendation.

As for the spring, it's tough to say based on just the spring alone. In order to confirm that the Series 152 can work, can you show me the shoe to which it attaches?
