Channel Balance, sash guide, top and shoe

Question

I have to replace the channel balances for the steel windows in my Florida apt. The one that looks like it fits is the 31 " 1/2 inch wide 377 series on your site.  It has a 3020Z stamp on it (which is the weight -20 lbs- I believe. The problem is that I can recognize the top 19-018 (my top piece is not in too bad a shape) however the shoe from my balance is broken and the flaring piece is cut off. The piece I have is "white" and yours seems to be yellowish.  It seems like the measurement of the two sides is 15/16" like your picture.  The building is from the 70's in Florida.
My question is do you think it is a match?  Does that top piece 19-018 always come with that bottom shoe 15-005 on this type of balance?  
Also do you recommend replacing the sash guides and take out clips also?  It states on your web site that Pan American was the company manufacturing steel windows, would that be in Florida in the 60-70's also?

Thanks, Remy Ayache.

To my understanding, Pan Am was very popular in Florida. The Series 377 fittings are Swisco's 19-018 Channel Balance Top with the shoe 15-005 Channel Balance Shoe, Winged. 3020 is the correct balance, however this does not mean it supports 20 lbs. 3020 stamped balances will carry a weight from 12 through 16 lbs. Do not be concerned about the balance color, this is a result of the resin from the mold injection. Also, if you need top sash guides, please take a look at 18-042 Top Sash Guide, Pair. However, it is not necessary to replace the top guides unless they are cracked or broken.
