Re: speedo reduction box
Albert.
Well, almost. You have a 69 Chevelle and it's a bit different on a few ratios than the Camaro! For a 4.10 rear end with F70x14 tires and a 3 or 4 speed manual transmission, you'll need the following: 3924098 8 tooth drive gear 3860342 19 tooth driven gear (neutral color) 3932220 Adapter I didn't see your reference to the COPO Chevelle above. Sorry about that! And by the way, GM didn't use a Stewart Warner reducer. That's an aftermarket item. Ed

Re: speedo reduction box
Thanks Jeff, those are the pieces that I have - so I guess I'm not missing any. I'll have to recheck it - again.
Mr.Rose - get your hiney to a SCR, you'll see why we need speedo's

Re: speedo reduction box
Our Chevelle with the M20 has the straight reducer rather than the right angled one.

Re: speedo reduction box
Our reducer has Stewart-Warner on both ends and is original to the car unless some sneaky devil switched it. With 4:10 gears you would be winding it pretty tight to go off the end of the speedometer scale. I found the speed warning buzzer handy though.

Ed..I've never seen anything but a Stewart Warner brand used on the Ass.line for this item.Both on survivor vehicles and in the manuals. Can you show paper or pix to contradict this?
