I replaced my MR-1 spindle and have parted out the original spindle parts. The only thing that remains is the original shroud. My shroud also has an aluminum probe holder bolted to the top which lets you leave the probe hooked up but stored out of the way.
I know that some people cut a notch out of these for better visibility. If you want a spare that isn’t notched you are welcome to this one.
I don’t think it makes sense to ship (being bulky and low value), so it’s free for pickup in Seattle (I’m near I5 exit 171, NE Seattle).
DM me if interested.
