Clutch slave cylinder bore sizes? 1" vs 1-1/6"?
Has anyone else noticed that parts stores (or at least RockAuto.com) list both 1" & 1-1/16" hydraulic clutch slave cylinders for our old GMC's?
Luckily I was wise in the past decade and went on a few buying sprees of anticipated spare parts, & bought both size slaves, which I now need - to replace an 11-12 year old unit that is leaking like a seive currently. But the question is... Which one is the proper size, and if they both do fit our trucks, which trucks get which bore size??? Is one size to give more leverage for a much stiffer/bigger clutch&pressure plate?
