Scuncio,
I have an 1: .833 also but mine has different part number 6477965. Do you happen to know why or the difference?

[luv2sixty9]

I did some research and mine is for a 1970 Nova with 4 Spd (Exc. Close Radio) and does the following:
Rear Axle Ratio - Rear Tire Size - Adapter, Speedo / 4.329
3.55 E70 x 14 6477965
3.55 F70 X 15 6477965
3.70 F70 X 15 6477965
4.11 F70 X 15 6477965

Scuncio,
I found a little info. on your part # and its for 1968, but it says to refer to chart in group 4.337 for additional model application. I don't have that chart....Dave

My car is a 68 Z/28 E70 X 15 with 4.88s. Should be the last gear and adapter combo in this chart.

Bill,
I have a 736 that I thought I didn't need, but according to your chart it indicates that I do. Now I'm confused. My 68 Z has 410 gears and E70-15.

According to my chart attached below it appears that I don't need an adapter. I would like to help you out but I want to make sure I don't need it. Dave

As long as your driven gear is the orange 25 tooth 3860348 is should work according to that 68 chart. The 69 chart I posted says you need the adapter. I never considered the gauge itself differed mechanically between 68 and 69 but maybe that's why the difference in the two charts.

I have 6476736 on my 68 L78 Camaro with 4.10s so I can confirm that application.
