Which center iron for 12AT?
I have a 12AT setup that I put on my SA but pulled off & decided not to use on this motor since I have a good hogged out Nikki on it. I may be getting a couple 12A motors, so I'm thinking about building a 12AT just for ***** & giggles. Which 13B center irons can I use? Is it just the 84-85s that I should use?

the GSL-SE is the only US delivered iron with injector bosses, and the water seals in the right place.

the 12A-T and RE-Si engines had irons that would work too

That's what I figured. I believe the 12AT originally used a GSL-SE center iron, just wanted to see what other options might be available. Thanks
