[Spridgets] Electronic Ignition

I've been running one in my 1275 for about 20 years.  Like I said in my two 
part post, the Lucas distributors are all interchangeable.  The one I'm 
running was NOS for an MGB.  The actual transistor block inside that big 
black box is a very universal part.  It is the same electronic module for 
the Chevy Citation, and Fiat, among many others.  If it ever fails, you open 
the box, remove the module, take it to autozone/pepboys/kragens etc, and 
tell the guy behind the counter you are working on the Chevy.  For about $11 
you get a new module.  Be sure to use the special grease when replacing it 
so that it transfers heat to the big aluminum box.  Overheating is the #1 
cause of failures.
