For internet's sake/googling help, I am posting this to help anyone else out.
Our 1986 Wesco furnace went out (Model 5131411) the other day and found a broken coil and bad sequencer.
Single coil - 5KW240V, 7434525
Dual coil - 10KW240V, 7434505
Instead of buying a full replacement kit we decided to purchase the restring kit. This is the way to go and should be more well known. I ended up buying 4 coils (2 2-packs) and recoiling all 3 coils since they are 30+ years old. Having a spare one in the end will be a great help in the future.
Restring kit - (2-Pack) Napco 5kW Heater Restring Kit, 240 Volt with Fuse:
The pictures above are exactly how our coils ended up looking after the recoiling.
