I don't know of
any 90 degree
inverted flare fitting that will simply screw into a master cylinder. As Joel stated, it's possible to carefully bend a tight 90, as I have done in the past. However, I found that drilling holes in the X members (on my '40 and '32) and allowing the lines to come straight out of the master has the advantage of keeping most of the plumbing out of site and harms way, along with easier and more direct routing to the front and rear axles, IMO.
