Repop Spartan horns now avail

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

You know about the tuning screw on the horns and how they can often get a horn working again right?

They show their Sparton horns and state they are correct for 67-71 B-body and 70-71 E-body.
70-71 E-bodies used only Prestolite HI and LOW horns as pictured.
I cant vouch for what came on 66-67 models but had thought Sparton came later.

Ive already tried that with no results.

Horns on my car are dated 11th week 1966 on an April 5th 66 SBD car

If you’re concerned with originality, have them restored.

100% dead nuts accurate is not my goal.
A reasonably close to stock appearance , function and longevity is though

Sounds good👍
