Guess I never knew there were different amperages on them! Always thought there were auto and manual versions only and no amp rating. If I am incorrect in that assumption then I would go with the 30 as you will be covered.
It's what the contacts are rated for.
I have available a 20, 25, and 30 amp starter relay.
Which one do I use for a 1969 Barracuda /6 ?
I've never heard of such a thing. Where are you getting this information? Or are you talking about the more modern so called "Bosch" relays?

2444443 Std. trans
Auto trans is 20 amps, std. trans is 25amps.

I still say this is nonsense unless you can trace it back to OEM. Anybody can put a spec on anything. That does not mean it's true. Ask yourself why would stick vs auto need different current ratings?
I bet both of those came from the same Chineseaoationized sheds with the same exact contacts internally

That IS the 30 amp I ordered and returned. Why the manual trans is rated 5 Amps more is a mystery to me also. I can only guess it may be a marine application compensating for a marine starter, but I’m not gonna hunt that one down.Interesting. The later style push on terminal vs the old style stud that I've seen, had an additional terminal for resistor bypass. I've always called them "Jeep" style. Dont know what all they were used on. Like this:e 39 ampe
