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, while the shorter bolts and thinner hoses go with the '86-94 calipers. The shorter bolt can also be found in the cars, as well.
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.
