Breather Assembly and Rear Engine Mount

[Joseph Gray <pinball@camalott.com>]

Hi All,
       I picked up a type I motor for my fastback today so I have a couple
of questions. I don't care about originality (form follows function). 
       Is it possible to to drill and tap a type I motor to use the type III
breather/oil filler assembly?
        How important is the rear engine mount? I'm talking about the upper
one on my 68 fastback, not the lower bar on the later models with no frame
horns. 
Thanks,
Marty
