drive gear
I have an auto 74 Vette, auto, stock tires. I'm putting in a 383 crate and changing the rear gears. I'm taking the stock 3:08 out and putting in 3:55. I'm told I need a GM P/N 1362048, black 40 tooth gear to have the speedometer stay accurate. It has a 30 tooth input sprocket, and tire diameter is 26 1/2
Problem is I can't find one. I've looked in all the normal sources with no luck
Can you verify that is the correct tooth gear, and guide me to where I can purchase one
Thanks Len
