Help ID my distributor, I have a part number!
 

I am less than enthused to find out that my engine is not the one born with the car. I have a 78 SC...but my engine case is an 82. Im trying to find out just what kinda frankengine I have. In any event, does anyone know where i could look to match part numbers to the item. Right now, im trying to find out what type of distributor i have.
the part number is 0 237 303 003

this all came about because i bought waynes book(101 projects), so then I start doing some of the projects...

Now i know just enough about my engine to be a little ticked. Oh well, i might as well do the best with what I got...

as always, any help is greatly appreciated.
