Is there a chart out there available for speedo reducer applications and date coding. Also does a 69 Camaro with 15” tire/ 4.10 rear gear require a reducer ?? Thanks SYC .

I believe a 4.10 requires a reducer. A 4.11 gear in a Corvette does because the tail housing can't accommodate a gear big enough for a 4 series gear.

I can look that up but the chart starts with transmission & exact tire size...Joe
