Banjo Bolt and Hose Info
Here's a few pics to show the difference between the banjo bolts and hoses. The longer bolts and thicker hoses go with the '84 calipers (typically 720), while the shorter bolts and thinner hoses go with the '86-94 calipers. The shortest bolt can be found on the cars, but they're a bit too short for the best thread engagement.
The shortest bolt is about 22-24mm. The middle is the best at 27.5mm(Dorman 13912). The longest is 30mm and is not recommend unless you use the matching hose(720).
***It is very important that you get the correct bolt for the hose you use. There are lives on the line when dealing with brakes. If you don't have the skill or experience to do this work, seek professional help.

Rockauto lists this number as an OEM replacement: 11569590 It basically comes back to the same dorman part above.
You can also find both bolts on Amazon.
NOTE: I picked this up from Doug S(Morrisun) on a 1200 brake thread. If you happen to need the shortest option, here's some info about it. Thanks Doug!
"The banjo bolt for the Sentra Caliper used in this brake upper grade is a RAYBESTOS H5381 {#463560E00A, 46462SE0000} $3.15 OR NISSAN 463560E00A for about $5.85, both available from rockauto.com"
This is an example of the preferred hose that uses the shorter banjo bolt. Any parts store should be able to cross reference the part number or look it up by the application(make/model) shown in the picture. Note: this is the 2WD option.
