I'm looking for a 90 degree speedo adapter for an M21 with 3:91 gears. The GM part number is 395430 and the ratio is .866 PM with what you have or any leads.

Thank you

Sold the one I had long ago. I suggest you try any transmission rebuilders near you or on the net. these were also used on Chevy and GMC trucks.

I have one, but I think it is stamped 1.1:1 or something similar. From what I understand it was NOS when I purchased it, and I have not used it as I have an aftermarket 5. If interested PM me.

Could Olds have used a Stewart Warner made speedo adapter as original equipment?

I have a .882. That is a .08 MPH off at 50MPH or 1.6MPH off at 100MPH.
Not a noticeable difference while driving down the road.
Turns freely with no issues.
$75 shipped to the USA
Will trade for a 1.200 or close to it.

Thanks for the offer but doing a concours restoration and I'm holding out for the right part.
