The teflon lined hose requires the high dollar (in comparison to standard AN hose) fittings with the ferrule that has to be inserted between the liner and the braided stainless. Like a thousand little pins draining the blood from your fingers, one tiny hole at a time.

Definitely a viable possibility. With all the crap I went through on mine getting hoses to work, I probably should have done this myself. I guess I chose that moment in the project to save a few bucks. Go figure.

What all did you have to do to get yours to work with stock hoses? If you don't think that it was worth it, I might just go with the AN hoses and fittings to save the aggravation.

Also, how did you figure out the correct length for the pushrod that connects to the brake pedal?

I got the hydroboost bracket flipped, drilled the bottom 2 holes in the firewall and the pedal assembly, opened the hole in the firewall for the retaining nut, and mounted the hydroboost on the firewall. Now I believe the only things left with the hydroboost is to figure out what I am going to do with the lines, figure out the right length for the rod that attaches to the brake pedal, figure out if the proportioning valve that came with this hydroboost unit will work for my application, and plumb all of my brake lines.

I think that I have a list everything if I don't end up trying to use stock hoses

If I go with the AN route for the hydroboost lines, these are the parts I believe I will need:

Adapter from 18mm w/o-ring to -6AN
Adapter from 16mm w/o-ring to -6AN
High Pressure AN Line from pump to hydroboost
High Pressure AN Line from hydroboost to steering box
Low Pressure Line(either AN for appearance or just rubber hose) from hydroboost return to pump
Same as above for steering box return to pump
T-fitting to join the two return lines

I believe that everything is there. If I am missing something feel free to post it.

Now I just need to source this stuff and figure out the right sizes for the return hoses and T-fitting. What kind of hose can I use for the return line and T-fitting?

I just mocked up my engine crossmember and motor mounts Tuesday night and I will begin welding them in tonight along with fabricating a crossmember to use with the stock transmission mount. Finally, no more blocks, jackstands, jacks, chains, or hoist locating it in the frame rails!

I will get pictures up when I am finished with the transmission crossmember hopefully tonight or tomorrow night.
