I recently rolled an 04 Jeep Liberty 8 1/4 rear diff (disk brakes and 3.83 gears!) under my 80 /6 Volare. As some of you may know already, the F-body speedometer gear/housing is completely different than the old design and a bear and a half to get different gears for. So I swapped for the old metal style housing with a 39 tooth gear. I then pulled then old speedo cable out. So heres my problem; I need to order the right cable! The old one is roughly 60" but the trans end needs to thread on now. Has anyone done this swap before? After bumbling around the internet for the last week, I havnt found anything definitive as far as the correct part. Any help would be awesome.
