Bought the conversion cables off of LMR. I’ll try to find the exact part in my purchase history. If I find, I’ll edit this post with the number.
On the ‘86, there is no conversion/ welding needed for the handle……. The new cables just have the correct end to attach to the new disc brakes as opposed to the drum. At the handle part, I’m using the original “t” or “splitter” whatever you want to call it. One connection from handle splitting to the two cables going to the calipers.
I can get it to grab, but there is still a slight roll on my driveway. Tighten the nut on the threaded rod gets it better, but at full adjustment, I still have slip.
Edit:
Here are the cables I used:
