Johnston - OSO Publishing 1997, ISBN 0-9647521-1-5. He recommends the Hoffman
end beams (part #SH-EB-1), which require some cutting, trimming, drilling and
tapping of the MDC frame - but no soldering - as they add extra adhesive weight.
The alternative, he suggests, is to cut off the coupler pocket screw mounting
post and drill out #55 for the Kadee self tapping screw or #56 and tap 0-80 for
a machine screw.
Fit the coupler with a 0.05" styrene spacer to bring it to the correct height
and fill the gap 'twixt coupler and frame with a shim of styrene. Finally, trim
off the back of the #714 to prevent it fouling the truck as it swings.
It looks good in the photos.
