Rear brake drum conversion

[Spikedog08]

So I am looking to get rid of the drum rear brakes this winter on the 8 3/4 in the convertible and was looking for ideas on what kit to buy?  I see Mancini Racing has some kits available and I can drive there to save on shipping.  Hmmmm wonder if Roseville has kits?  Can drive there also . . Thoughts? 

Also how easy is it?
