The booster will be too low. You will have to fabricate some sort of a bracket to raise it. This has been covered in past threads if you do a search.

I don't know of anyone that has tried a Granada booster. Most of the members that have done the disc conversion have used the replacement booster/master cylinder combo that a number of vendors carry for squarebirds. Does your '59 have an under hood booster or the Kelsey Hayes one under the dash. If you have the under dash booster you will have a problem with the pedal linkage. You will have to use a hockey stick type of linkage to replace the original one. Check out Ray Clark's (yellowrose) thread about his '59 conversion.

Look for banjo bolts on the DISC BRAKE KIT VENDORS websites. Unless it is cataloged by direct application and is on a disc, you are hard put to find certain parts.

Is there a speed shop in your area?
