there are lots of fiero owners that want to stick with the 2.5 or 2.8-3.4 but HATE driving them on the interstate.if someone made a bolt in mount and included axle numbers and general info on ways to link the speedometer im sure it would sell well.i have a good 2.97 4t60 i need to install but i don't have the ability to build mounts and guess which axles to use.

I can help with the Axels

What should have been an easy swap has turned into a real problem. First it was the Axels. The only place that I found for the correct axles was at Auto Zone part numbers are: Left side 8471N Right side 8430N. Other part stores will give you the axles with 27 splines and you need axles with 33 splines to do the job. The part numbers from the old instructions that you will find seem to be the 27 spline ones. It seems the part numbers have changed over the years.

Then I could never find the governor cap as most 1980 cars were scrapped in the cash for clunker run they did years ago. Only option I found was to go with a Digital Dakota converter box. This managed to get the speedometer working but not the cruise control.

Since this was posted I did manage to find the governor cap which cost me just as much as I paid for the transmission.... but now the cruise control works.

if you do the dakota next to the speedometer it will cause this if you do it by the ecm it will work. I found this out long time ago.
