Where have all the Magnum parts gone?

I wanted to run a whole LA front setup from T chain cover out.
I wanted to run something where I could run factory style hoses rather than the hose barb and clamp setup most custom ac setups run.
At work I see too many of the custom made ones with the barb and regular hose clamp that leak at the shop I work at we don't mess with those, mostly they are on buses that have the ac hung on by the bus company when new...
Besides those look like crap and I hate getting my wrists caught on the hose clamp tails while doing other work
