I have the carbs, linkage, fuel log, etc.
I think the only unspoken for bk/bjs are 63 dated.
The only Medium Riser intakes I have are a C7-A and a no number one.
Pm me if you want to get put on the list to have the carbs restored. I do not sell cores, only finished stuff.
If original non-matching, I do have a pile of BD carbs which would probably suit your usage better.
