Disk brakes, heater.

["Herold Faulkner" <faulkner@redshift.com>]

Sprigiteers,

Can anyone out there tell me anything about disk brake conversions?  Like
specifically should one also replace the rear drums with larger ones to
maintain balance?

Has anyone tried Kevlar pads/shoes?  What are the advantages and
disadvantages?

Finally, does anyone have any idea what a replacement heater assembly (used)
is worth.  What should I plan to replace (core,etc)and what is likely to be
missing and hard as all getout to find new or used (control switch?)

Thanks,

Hal
