Looking for a a 71/72 manual transmission, 90 degree speedo adapter part number 396338. Has a .785 ratio. NOS would be cool but used is fine.

These are as hard to find as hen's teeth. You could try transmission rebuilders. Also these came on Chevy trucks as speedometer correction ratios.

Will see. I’ve had a few parties reach out.

I will try and remember to lock this weekend at my parents. I started organizing my dads garage and found 5 of the reducer speedo adapters in a coffee can. I remember some being 10 and maybe 20%.

Thanks Jeff. Please advise. Al

Did not read your request properly. These are not 90 degree. I have .944, .974,.1.05, 1.2020, 1.30.If these work for you or anyone else. $40.00 plus shipping. Willing to post in for sale section if you can't use any of these.
