Randy I was just talking about the bracket that the union attaching the rubber hose to the hard line is sitting on top of. I get it now...there is a nut welded to the rear.

Here's another question. Are your hard lines just standard inverted flared steel lines? Are those stock Mustang rubber hoses? I have '97 camaro discs on a '68 camaro 10 bolt. I ordered stock camaro rubber hoses and it threads on fine to my hard lines, but the flares on the hard line and rubber hose do not look like they will seal.
