Correct horn for 69 barracuda

[RJK3]

I have a member interested in some horns I have up for sale.
I have both sparton and prestolite models available. Can someone tell me the correct brand for his 69' Barracuda?
Thanks in advance!

Mine appear to be prestolite and have no reason to believe they are not original. Mopar used both so if one vendor was behind on shipments I see no reason the other would not be used. Not fact but opinion.

Thanks.
In the research that I have done, I've seen both offered. Wasn't sure if that was legit or not.
