If your pins measure 0.866, then a rather common reamer should do the job, pix of one attached, not uncommonly found at larger antique car flea markets as it also is used for Chevrolet and GMC trucks and Corvettes thru 1962. It's a 0.868". Note that Packard was very emphatic in their shop manuals that if the bushings are oil-impregnated, they should be burnished and NOT reamed.

All else failing use a good micrometer and measure the diameter of the new pins, and then head off to a good machine shop supply store for a reamer. In the absence of other advice, I'd think about a 0.001"- 0.002" clearance for lubrication film.
