$100 buy it now seems pretty cheap for all of the gauges and wiring in this......

The wiring is worth that much, if it is intact and unmolested. Which it probably isn't, or it would be priced higher. "If it sounds too good to be true..."

I purchased one dash off of ebay. The wiring was butchered so bad, It was a joke. But all the other pieces seem to work fine. Clock, tach and ammeter were what I was interested in. Sold the rest in pieces and paid $15 for those 3 pieces. As arne said I could be worth a lot more in pieces.
