OK, my speedo cable melted to one of my header tubes, i have a 460 so its pretty tight in there and i didn't notice it till last night. I removed the speedo gear from the tranny and noticed how hard it was to spin, then i swa the melted part, tried to free it with my drill but that just twisted the cable right off the end. How hard is it to swap in a new cable, and can i use the cable from a 4 cyl. fox? AOD and C6 tranny gears are same so thats not an issue.
