i am swapping a '92 posi 3.42 pbr disk rear (yay! i found one!) into my '86 that had a 2.73 drum pegleg. i will be using the stock front calipers and rotors for now
my question concerns the brake lines. i am looking at earls or g-stop lines (hoses) and wondered if the threads and lengths of the hoses are the same for either style?
also, i know i will need new rear lines and i already have the correct conversion valve, will the hard lines from the conversion valve to the master cylinder swap or is there a thread difference there?
i also know i will need a new parking brake line.
thank's in advance for your replies!

There is no thread difference (if you have the correct proportioning valve), front or rear. The proportioning valve will bolt up. Purchase Earl's lines, which you can see in the following link:

The set that you'll need is Earls-4D-8992-F

i noticed on steve spohn's site that he sells a master cylinder for 1984/1988 4 wheel disk cars, is there a big difference in the standard disk/drum master cylinders and the 4 wheel disk one? could the different ratios pop a seal somewhere?

 

Nothing to be concerned about (check the first post in the following link for an eye opener):

very interesting,
i was always a fan of non power brakes anyway. the heavier pedal feel is actually a plus for me.
thank's again James!
