I'm replacing the upper distributor shaft bushing on an early F engine distributor. The new Toyota bushing is 15.88mm OD, but the old bushing is 15.80mm OD. So I'm thinking the easiest way to go is to open up the hole in the distributor housing. It turns out that a 5/8 inch hole is exactly 15.875mm, or essentially 15.88mm. Seeing as how that's not very much metal at all to remove, I was thinking a new 5/8 inch drill bit will open the hole up nicely, and stay centered. But I've also read that a reamer can be used to slightly enlarge a drilled hole. What would be best? Any input would be appreciated.
I'd really like to figure this out so that I can resurrect the other six or seven early distributors in my inventory. I have at least 25 or 30 new Toyota distributor shaft bushings to work with, but they all have the same 15.88mm OD. From everything I've read, most of the early F engine distributors are sent to the trash heap due to worn upper shaft bushings. Excessive lateral play at the top of the distributor shaft leads to constantly varying dwell and highly inconsistent spark. Some of the early distributors are kept alive by installing Pertronix electronic ignition set-ups, which are more tolerant than points for distributors with excessive lateral play, but I'd prefer a solution that would allow for points.
