As you know I am using Timm Coopers disk break conversion. I did not buy the kit but instead bought a complete set of castings. Tis has resulted in lots of fiddling around trying to figure out what fasteners to use. Lucky for me the School Bus is located 2 blocks from Lamorna Garage and 1 mile form Tacoma Screw.
It took me several hours but finally I have 1 of 4 done for good. I should not need to do any more work to this hub. I hope the rest go faster.
