WTB: Speedo Adapter Box w/1.300 Ratio

I'm looking for a Steward Warner speedometer adapter box similar to the one in the picture with a 1.300 ratio. The ratio is stamped on the lower pad in the picture.

If you don't have any luck finding a original one you can get new adapters here that look the same.

Re: WTB: Speedo Adapter Box w/1.300 Ratio

Second on the www.transmissioncenter.net comment from jasons. I needed to correct my speedometer on my '71 4x4 after swapping from stick sm465/np205 to a 350TH/np205 auto. Plug n play, no muss, no fuss. Look for speedometer ratio adapter. Speedometer is dead on with my Garmin GPS now.

I'd appreciate it if you folks could look for any with a 1.300 ratio.
