400thm speedo gear thingy for 4.56 gears?

Ok, so I don't know what it's called...but I need the piece that goes on the speedo cable at the tranny, to correct the speedo in our '69 Camaro with 4.56 gears...doesn't have to be NOS, or original, but I need one...I keep tellin' everyone our Camaro runs 140+ in the 1/4, and no one believes me, so I guess I better get it fixed...plus, we're really rackin' up the mileage at this rate!

4.329 Adapter Assembly, Speedometer Driven Gear

3932220 1969/All TH400 with 4.10, 4.56 or 4.88 Axle Ratio

Stewart Warner - Stamped 0.7333

I'll bring one to Collinsville for you. Not NOS nor perfectly pretty, but ought to get the job done on a race car.

Come to think of it, can anyone post a pic of the correct reducer for 1968 Muncie applications? Not sure if the 90-degree style or parallel-offset style is correct. Thanks.

Anyone? Still looking for a reducer for the 68 Z. Thanks-
