I've searched the archives, but didn't find what I need to know. With the popularity of the t5 trans conversions, I'm sure I'm not the first person to run into this. I've got an '89 S-10 t5 that I'm planning on sticking behind the 261 in my '54. The problem is, '89 ran an electronic speedometer. Is it possible to convert this trans to a mechanical speedo? Is the tone ring for the PM generator held on the same as the mechanical speedo drive gear? Is it just a matter of swapping parts, or do I need to look for an older trans?
