300zx brake master middle fitting??

[njd07]

The middle fitting had that stupid plug in it, so I removed it and it there is no fitting inside it. if I install it as is its gonna leak for sure. so I read I could dremel my old 240 master and use the pressed in fitting from that. well I dremeled it only to find out I had the one peice cast 240 master cylinder, there is no pressed in fittings.

Then, I was searching ebay and found this http://cgi.ebay.com/ebaymotors/ws/eB...ksid=p3907.m29

bought it, tryed installing it, it threads into the 300zx master fine, but the stock fitting on the brake hardline doesnt have the same thread pattern as the female end on that ebay fitting. so I cant use it.

how else can I install the middle brake line without having it leak?? can I reflare somehow to seal? anyone experienced this?
