Default LQ4 brake vacuum source... anything but factory nipple available?

Title almost states it. But to be very specific.

I've got an LQ4 that I've swapped into an old Land Cruiser. I bought the factory nipple but it is HUGE. It is 5/8".

The nipple on my land cruiser brake booster is closer to 3/8".

I'm trying to make a clean install. So I'd rather not have a bunch of barbed fittings and hose clamps.

So the question is: Does someone make a replacement nipple for the back of the LQ4 in a different barb size?

Not sure if a Chevy truck one will work on a Toyota booster It would certainly make life easier if it did though.

I put a caliper to my nipple and it came up at .5". Then it has a "huge" barb.

I haven't tried a 1/2" hose but plan on it.
