Hydro boost swap trouble

[B_derK20]

I'm in the middle of swapping my '83 K20 to hydroboost and I'm now stuck. My booster is from an '82 K30 and I got a new master and all new hoses for the same '82 model year. My problem is that my hoses are all the o-ring style on both ends but my steering box looks like this picture. The high pressure port is 16mms flare style. The o-ring hose won't thread into it. Do I have the wrong steering box? I have an '88 V30 with hydroboost parts truck that I could take the box off of but I didn't want to tear it out if I wasn't sure it was going to work. Can someone help me out?

Thanks

After beating my head against the wall all day, I determined that I don't have some mutant steering box after all. It's an '83 so it has to be all metric because the return hose is the o-ring type. Apparently there are tap in inserts that convert the o-ring style port to a inverted flare type. That's what it looks like is in the pressure port. Now I have to figure out how to get the stupid thing out. Does anyone have any ideas on how to get it out?

Try at your own risk but I'd find a punch that will fit in the insert and pry in a circular motion until it comes loose.

Alternately you can re-flare the new hose. Just don't forget to put the correct nut on before flaring.

I'm trying to make some braided stainless steel lines for my hydroboost but I believe that I bought the wrong fittings. I have 16mm and 18mm to 6an fittings but the 6an to 3/8 seems to fit. Where can I get a 6an to 7/16 fitting? I've searched everywhere and can't find a set...

prob need to find a screw to thread into it, and some vicegrips to pull it out.

Did you ever get your HB sorted out?

[B_derK20]

Yes. I did just was suggested and used a small punch and kinda just used a circular motion and it walked right out. The new hose then threaded right in. The only thing now is I'm not really impressed with the hydro boost brakeing action. Even with a new pump and booster the pedal seems ultra firm and doesn't seem to stop any better than with the vacuum setup.
