William, Warren, I bought my 69 Z/28 in April of 2000. The original console and gauges had been added before I bought the car. I noticed the oil pressure sending unit fitting and line with the idiot light sending unit attached to each other. Never saw that before but no big deal, it works. 19 years later I see on Ebay the "EXACT" same setup block, nipple, line fittings everything as my car has. Never saw that anywhere but on my car. Still has to be a homemade set up but.................weird.
