How to Narrow an 8 3/4 Rear End

That ruler really does make life easy. You can get the ruler or a whole narrowing kit from Leadmine Product, 198 State Road YY, Tunas, MO 65764 Tel: 417 733 1012 (They had a website but it is down for some reason)

I used to narrow without the ruler by making wooden gauges so really appreciate using the ruler and a tape measure.
