Congrats. The radio was dealer installed; there was no factory radio. Blaupunkts and Beckers seemed to be the most popular ones installed by the dealers at the time. My 1973's dash made it unmolested until the late 80's, when the DPO (dreaded previous owner) installed a Japanese Clarion. I just picked up a Becker Europa II off eBay and will be installing it this winter. Another option is to buy a replacement wood kit and put the dash back to original as it came off the boat in new Jersey.
