I have no problem with mine. Not sure what you are talking about.
I know you and Dennis have issues but for the record, it was one of the better things I have done to the 66.
Let's end the BS. Chocko knows better but never allows the truth to get in the way of his commercial interest. There is a lot of this in this thread, and in the forums in general. All BS aside, owners of 6 cylinder 65-66 Mustang can upgrade their Mustangs brakes in 4 basic ways (The cost mentioned are for comparison purposes only).
-They can use a light weight system based on a caliper bracket cut from plate steel. The bracket mounts to the original light weight 6 cylinder spindles. The original light weight steering linkage and 4 lug wheels are retained. These commonly use components from several model or brands. Scarebird and SSBC offers such systems. The cost can be about $400 to much more.
-They can try to acquire 65-66 Mustang V8 spindles. These are fetching about $150-$250/set when they can be found. These can be the basis for installing the 65-66 V8 original equipment type Ford KH brakes. The KH kit is offered for $525. Again, the steering linkage needs to be upgraded (cost an additional $295). The the 6 cylinder 4 lug type wheels would need to upgraded to 14" or larger 5 lug type. If you have the spindles, this is a reasonable choice.
-They can upgrade using salvage "Granada" or 67-73 type Mustang spindles (drum or disc type). The parts are available to make this happen. These salvage Granada and 67-73 type spindles can usually be found for a lot less money than the 65-66 V8 type, but have incorrect steering geometry that may or may not cause problems. Again, the steering linkage and the wheels needs to be upgraded (as above).
-They can upgrade using a kit that uses purpose made Granada spindles that have V8 65-66 spec
suspension/steering geometry. This kit is offered for $525. Again, the steering linkage and wheels will need to be upgraded. A 4 lug version is available (still requires wheel upgrade).
Updating a 6 cylinder Mustang poses many challenges not faced with their 8 cylinder brothers (sisters?). This is one of the primary basis for the value difference of these models.
Rant over.
