I have this original GM CD Ignition box listed on Ebay starting at $9.99 with NO RESERVE. It will sell to the high bidder at auction end. This was optional on a select few GM cars in the late 60's and was available as a high performance unit from the parts department. This is a very hard to find original box.
Free shipping to paid member in the US.
