Im in need of a horn the for the car ( one died this past week) and I just found out they are now avail as a repop and sold in pairs

Anyone have an idea why 2 different part numbers for the kit , both kits contain both a high and low note horn?
And anyone bought them and can comment quality ?

Im not so sure I want to gamble on a used one and have it die as well
