Getting .001-.002 Endplay On Trailing Arm
Could I just take a piece of glass (glass is flat) and tape a piece of wet/dry sandpaper to it. Then take the shim and apply even pressure to it, slowly drag it across the sandpaper and then check the endplay again. Basically repeat the process until my endplay is between .001-.002? The shim will originally be just a bit larger than what I need. Unfortunatly I don't have access to a parallel grinder. Thanks

Crocus cloth works better than regular wet and dry and mineral spirits is a good solvent. Use a figure 8 pattern for more even results. This is a very common process to do and is often referred to as "dressing" a thrust washer or in this case a shim. You can use this method to dial in the front wheel bearings as well as the rear ones you are working on. Any more than two or three thous should be ground to ensure parallel surfaces.

The biggest reason a parallel grinder is used is to keep both sides of the shims and spacers parallel with each other. Sanding on a piece of glass will true the one surface but will not quarantee that it is parallel with the opposite end.
