For sale is a brand new, never installed/used Gen I Dynaspark optispark unit. Item was purchased to put on my car (as a preventative measure) but I sold the car. Unit fits 92-94 Corvette, 93-94 Camaro, Firebird, and TransAm, and early 94 Caprice. Asking $500 obo (plus shipping)-this unit costs $600+tax (another 30 bucks when I bought it) if you were to buy it elsewhere. Save well over $100!
