Not an issue Jerry, the classic aluminum AN fittings come with a 3/8th's NPT. That matches the pipe thread in the steel Yor-Lok and adapt that to any AN thread you want to use. In my case I will be using the -8's. I will get pics and part numbers when I get all of the fittings gathered up. I am in process on the McMaster Carr order and will be ordering the NPT to -8 adapters from Jegs this weekend.
