Re: cup plugs
Alot easier to get em at a REAL parts store...
Not sure I know anything about this "tapered" though; only been doing this about 40 years or so though, I'm kinda inexperienced, maybe that's something new?

Re: cup plugs
5/16 as 8mm here www.ebay.com/itm/150610245935
3/8 as Dorman 555-115
Not under a buck a piece at your local store like "they should be" but there you go.
Obviously, you'll save time by just tapping for a thread-in plug.

Alternately, a piece of iron pipe machined down makes a nice cheap bushings driver.
It's guaranteed to go in easier than any F-body T56 tailhousing bushing.
