SBC power steering pump question

I just installed a mid 80's GM pickup steering box in my 1960 Chevy half ton. When I got the box from the local pick a part I probably should have grabbed the pump also but I had several good ones in the garage so I didn't. Now comes the problem around 1980 GM went to metric hoses with o-ring ends. My question is can I pull the fitting from the later pump and put it in my old pump replacing the reverse flare that is in it or do I need to go get another pump? Or is there an adapter to use an old style hose on the new box or new style hose on the old pump?
Thanks

I have done this fix a couple of times-I have spliced the end that fits the pump to a hose that fit in length, but didn't have the right end for the pump-just cut the metal tubing and used a 3/8" (or whatever size) compression fitting to join the two metal lines.

 

I think you can change the pump fitting to the one you have and see how it does.They are all made by the same company, so go 4 it. You can also modify the valve inside the pump to lower the pressure. I used the gm valve in a late ford pump and added shims to change the pressure and it works great. Need help, PM me.

 

I have changed the fitting before, but if I remember corectly there may have been issues with the pressure. It's been 12 or 13 years so... I don't think it was a problem though.

 

Thanks guys. FYI NAPA does have adapters to go from the male to female inverted flare but not to the o ring type.
