Note the different caliper--pad philosophy, showing how GM has evolved their brake program.
The older disc brakes--like the amateurish Little Shop of Horrors kit uses--had the pads trapped in the caliper; then GM properly braced the caliper so it didn't twist from brake-torque reaction. The crime LSoH commits is that they don't brace the caliper like GM did.
The newer disc brakes--that are used in the Street Truck article, conversion parts made by Freeman--trap the pads in a second, solid iron bracket with no rubber O-rings or screw-in pins, that was designed from the beginning--by COMPETENT engineers--to accept brake torque on the inboard side. The caliper itself has no brake torque, it does nothing but clamp the pads. The adapter brackets that locate the caliper and transfer brake torque to the steering knuckle or the rear axle housing may or may not be stiff enough (I don't know...but they seem to be OK) but unlike the LSoH kit, they don't change the way the rest of the caliper mounting was intended to work.
LSoH needs a biitch-slap for not understanding how GM set up the older calipers.
