OPTI questions

What is the updated part number with the three weep holes for the 93. Was the 94 the same? Are the manufacture of the rebuilt of any value?

The last new GM OptiSpark for your application was GM #10457702. It is discontinued and replaced by a unit, GM #19212299, which is officially "remanufactured" but may actually be a new unit (sometimes GM will sell new units as "remanufactured" so that they can apply a core charge and get cores returned). However, the 19212299 is quite expensive carrying a GM LIST price of $940, plus $75 core charge. Aftermarket OptiSparks are quite a bit less expensive. Are they as good as the GM unit, remanufactured or otherwise? I doubt it.

I think they can be obtained through Delco dealers. The Delco part number for this piece is the same as the GM part number. I do not know what company manufactures these distributors or components thereof.
