That is a hard dude to find.

IS this the SW straight through adapter?
I will have to look at the shop today, I know it was a .777 I just took off a car 2 days ago.

It was the angle adapter I was looking for, but since that is the right ratio I don’t know why that wouldn’t work. Let me know and thanks for the reply!

Sorry it's a model 777 - ratio .7333

Thanks for checking.

If you're flexible on ratio I have an original AC 0.833 angle adapter.

[firstgenaddict]

Tony can you send me a photo of the .8333 unit if the OP is not interested?
I am looking for a .8625 (I think) well I know the number started with an 8. lol

FWIW I also have the following two .9743 and 1.2020 Stewart Warner adapters (straight through with offset input and output)

Sure, I'll post a picture. It's in good condition with the original finish.

I’ll do a little math and see if that will work. Thanks.

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

68 4 Spd Chevy, Chevelle, Camaro with 4:10 ratio with 7.35 x 14 tires, F70 x 14 tires
68 4 Spd Chevy, Chevelle, Camaro with 4.56 ratio with E70 x 14 tires
68 4 Spd Chevy, Chevelle, Camaro with 4.88 ratio with E70 x 14 tires, E70 x 15 tires

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

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

I've got a couple not really sure what they are. Just took them off a 71 M21 and a 72 M20. Here is a couple photos. Larry

If you want to sell the .8241 I am interested.

[STEFS]

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.

Just found these that I've had squirreled away for quite a while...if they do you any good.

[lzdick]

Also found this unit without the offset. Not sure what I have here...does anyone know?

Thanx,
