This seems to match up with what you guys have listed above. Just need to check OD and ID specs.

Don't forget a decent set of seals either

Don't forget a decent set of seals either

Any recommendations for seals?

Been way to long for me to know what advances in materials or brands available for AMC stuff.

I'll let someone else take that one.

I had my machine shop machine mine for positive retention Viton seals. He said they are vastly superior.

I have seen it done on one of the Motortrend shows (maybe Hot Rod garage?) on a bench, with a special tool that was about $75 (I think?), and considered doing it myself but he was doing my heads anyway and it made more sense from him to do it.
