The old Bendix four piston look a lot like new Baer and Wilwood brakes, 
but there are some engineering differences in the way they seal. The
old Bendix are really bad about leaking and wearing the bores to an egg 
shape. Newer materials has something to do with wear also. It's common
to bore the Bendix calipers out and install stainless steel sleeves.
All rebuilt ones that you find today will be sleeved. Heat's probably
the main culprit -- those things used 1/4" thick solid rotors. If you
do use them, have the rotors drilled and slotted for better cooling. As 
John Elle mentioned, the single piston brakes are just as good or
better than the old Bendix four piston. But the AMX kit you mentioned
to me in an e-mail will bolt on. 

For those who don't know, Aero makes a modern front disc brake kit with 
an aluminum hub. It's a bit pricey at around $850, but all new parts
and bolts on any 1950-83 AMC even though it's listed as AMX/Javelin.
One of the guys on the AMC Forums (www.amcforums.com) is a dealer and
has some pics up. Go to the Forum and search the brake/suspension
section.

WSC Motorsports makes a rear disc kit for the AMC 20
(http://www.classicone.com/wsc/catalog/amc/amc_per1.htm). It's $759 but 
includes everything, even calipers with parking brake built in. You can 
also use one of the universal kits from Speedway
(www.speedwaymotors.com). These come with weld-on caliper brackets and
slip on rotors (slip on like a drum). Use GM calipers with or without
parking brakes (you can use front calipers). To use these you cut the
drum backing plates around the axle tube flange to retain the axle and
seal.
