Hi Keith,

Found my 1978 copy of the Illustration Catalog Opel and GT Models Thru 1975

Looked up Fuel System 1975 Model 50 and there is the injector: #36 Injector, Fuel Parts Group 817-------

Went to the Parts Book and foud that it only covers to 1974 Models so no fuel injection section *!!*

I think I do have the 1978 Parts Book so will search for it.
Till then maybe someone will be able to find a parts book with Parts Group 817--- in it. That's where the part number is.
