Early LA eng by pass hose

my 72 340 used a 3\4" brass Iron pipe size nipple that was 1" OD. It was a standard nipple that I got from my assorted plumbing fitting box, I just cut it down to 1 1\2" and put er in there. Sounds like thats what you have. Then I got the hose from the local NAPA store, the only thing is I wanted something to make it nice like some stainless braiding but this size is unique to SB Mopar engines.
