it's as much direct bolt up as in a production year which did offer a big block (or a car that originally was a big block), you still need all the same parts, no mods required..how bolt up can it get?

All the parts are out there its just a matter of how much you want to spend or how creative you can get with stuff you can find at the junkyard and swap meets.

What does you guys score cards say??
jk both have valid points.

Once I figure out what power steering pump I'm going with to handle the load of the jeep box and hydro then I'll figure out my lines.
I'd like to go with the Hydratech lineset since I have their hydro unit but i have a hard time shelling out $200+ for hoses. We shall see.

If you install a fluid cooler inline with the return line to the pump, so the cooler cools the fluid before it gets back to the pump...a new stock pump will probably last just as long as a pump with no Jeep Box.

Make sure you transfer the spring and plunger from the pressure valve in the back of the pumps when and if you change.

It actually ended up a bit lopsided. I don't know how, and I've never had it happen again.

Just out of curiosity, what uses a 37* flare?

The stock tubing is NOT seamless and thus a single flare will leak, guaranteed. THAT is what this is all about, so that otehrs don't start cutting up their stock lines in the hope that they can flare it, which they can NOT without spending at least 400$ on a proper tool. your info is a danger to anyone working on these cars, will you pick up the tab for new lines after they cut theirs up and discover it's now completely useless?? It's not about who has the best tools mister, it's about who has the PROPER tool for the job, there's a world of difference.
TT, it's not a big deal, it's only a line for your steering and brakes. How dangerous could that be?

37* flare is for AN fittings and AN stands for Army Navy it was a joint standard. For our metric friends AN is essentially JIC or Joint Industries Council.

45* flares are for Plummers...

That's interesting to know, the JIC part I did not know.

Would you classify one as better than the other?

for automotive use they are functionally equivalent. For aircraft use I don't know the answer. Maybe one of the military or civilian aviation forks here will know.

For the return line would the 5/16 o-ring type fitting work...

I suppose I could run off a batch of the correct part on the lathe....

37 degree flares have a larger sealing surface, simple geometry..however if you don't know the diameter of an oval you could be fooled by this one also.

AN flares use ordinary UNC threads.

AN is indeed army navy and it's the same thread and 37 degree flare as jic however an hardware has to meet higher quality standards and the thread profile is a little different also (better quality).

It was developed for ease of use w/ hoses and hard line connectors, indexing the fittings and hose by the equivalent hard line size. This makes grabbing the right hose and fittings for say a 3/4 OD hard line real easy as the hose and fittings of size dash 12 (-12AN) have the same ID as the hard line and a -12 tube nut and sleeve will fit that hard line perfectly.

inside every oval there is a circle trying to get out... Sorry Mr. Kubrick

I believe I recall that AN fittings used on Aircraft have to have "traceability".

yeah, and they have a shelf life too, just like the bolts. They come individually packaged w/ codes on it, certificates and all. Not needed of course for our applications but it does tell you something about quality, there are some brands which are aircraft quality and a whole bunch which are not. The cheap hose ends are also much easier to assemble than the more expensive stuff.

Don't get me started on that Airplane stuff I sold my 182, the next thing you know I'll be renewing my subscription to Trade-A-Plane and be POORER than I already AM!!.

I'll be back in the airplane hobby soon enough... I promised my kid that as soon as dad finishes grad school (PhD Comp Sci) he will buy a nice twin to shuttle her back and forth to college...
