pgold got a reaction from Shep69 in Rear wheel cylinder size .
Shep, I ordered mine from Richmond Brake and Clutch in Melbourne 03 9853 2113. No stock in Brisbane at the time. Pads to suit VT Commodore callipers fitted to my 69 $137.45 delivered to Brisbane. Much cheaper than EBAY. They may be closed with the covid 19 lock down at present. DP31158C may be the pads you need.
