Quit your whining . . .

If you're doing much for engine work . . . changing cams, pinion gears, etc.  You really should have the neat little kit available from Jim's.  You get a couple sets of pins and some detailed instructions (and chart) that tells you how to measure your camshaft and pinion gear.  This way you get the correct cam / pinion gear combination so you don't have a "whining" or "clicking" gear case.  You don't want binding or undue stress on your pinion shaft, bushings or bearings.  Retail: about $20.00
