I know I am a week late on posting the pics, but hey I was busy. Here are some shots of the rear brake setup.
The caliper is at the 9 o'clock position. (optimum). The direct bolt on kit available from Japan that has a machined bracket (more expensive kit) places the caliper at the 11 o'clock position.
This pic shows the small amount of metal I trimmed off the lower arm in order to clear the parking brake assembly.
The caliper is also mounted upside down in order to provide the proper cable pull direction. It is unconventional, and requires the caliper to be rotated to the 12 o'clock position for bleeding. Not a big deal in my world as bleeding the brakes only happens how often? The Japanese kit does not require the caliper to be installed upside down as there is enough clearance at the higher location. $3k was not a reasonable price for a rear disc brake conversion in my opinion. If you are not using the parking brake then mount the calipers the normal direction. Just remove the parking brake assy from the backside of the caliper. When the car is jacked up from the rear diff everything gets real close (rear shock, axle, caliper and lines). Once on the ground there is plenty of room.http://victory50.com/index2.html
Item 25 is the bolt on rear disc kit I mentioned. With the exchange rate the kit is roughly $2800. Ta ki for sure!
I called the builder of the brackets and he has more to include the stainless steel lines to go with it as well. I modified Z31 cables to work on my application.
Hope this helps.
