I still think the little spacer is going to be the solution. I read about some 'Corvette-style' mc's last nite, & the site mentioned it included an 'adapter' for the different style mc.

This site mentions the different mc's, the deep-hole and the shallow-hole. Don't see the site mentioning including the adapter right now(gotta go meet my walking buddies).

Ok, here's a site that mentions, very briefly, the deep-bore adapter

And here are 2 pics I found on another forum's site that show how the same mod can be done by adapting a longer-or-shorter pushrod out of the booster to accomplish the same thing. Pics show 2 diff. boosters--older one for a shallow-bore and newer one that adjusts for either mc by adding/removing a screw-on booster-rod-lengthener/shortener [Still haven't found a pic of an actual bore-plug adapter--it is so simple to make one. I experimented w/a round wooden rod from Lowe's to get the correct length:so cheap & easy to cut and trim, and cut another one if you cut it too short, etc. You want to have a tad of clearance between your booster-rod and piston-adapter (or piston itself if using a shallow-bore mc)].
