Do you sell my Jeldwin Balances?

Hi

I purchased four Jedwin windows that were used to put in my home. They are from Lowe's the Atlantic final impact window. They are 52 x 62. I'm looking to replace the balancers in them. I believe they have spiral balancers in them right now and one in each window is broken, the outside casing is measuring 29 inches and they measure 5/8.

I was wondering which balancers I should purchase and what shoe I would purchase with them too. The only thing stamped on them is the number four the color of the rubber stop looks to be yellowy brown , I have attached pictures if you could guide me into what I should be buying to repair these windows. 

Thank you,

Ken 

Thank you for replying to my question about window balancers I believe we will go with the black tip one as the sash way more than 40 pounds on each window now for the brake shoes I have included pictures of the brake shoe which we have removed. 

We found numbers inside it that say, 4610108 the brakeshoe that we removed measures half inch thick 1 inch wide to end, 2 inches long I also found on the window balancer some numbers that were embedded on the casing, which read E 29M 273L I was not able to find anything on the website for brake shoes that are 1 inch wide. 

If you could help me with what brakes shoe we should be ordering to go with the balancer that you have recommended that would be great thank you for your time.
