I have an 87' with a 700R4. I recently replaced it and connected the speedometer cable thru the 90 degree adapter. The speedometer had been disconnected a few years back and it didn't work. Long story short traced it down to the adapter. I'm guessing the gears inside are shot as it will spin only on side. I connected the cable straight to the transmission and now the speedometer works, but with out the adapter it is off. The adapter shows a 1:0.90 ratio on it. So, I started trying to find one and seeming pretty hopeless. I've seen a couple on eBay but seems pretty expensive. Are there any other options? Oh here's an image what one looks like.
