I plan to do it to my '87 as well. I'm pretty sure the boxes are the same size as far as the hole is concerned, or very close. I'll also replace the internal battery box with the external one - have to cut a hole for that - and get the board with the XLR & 1/4" jacks. There's another, albeit small, hole. Much easier than replacing an OP24 with an OP-Pro, btw. twistedlim Posted 2010-01-19 7:58 AM (#382122 - in reply to #382120) Subject: Re: Swap OP24 for Optima Joined: November 2008 Posts: 1119 Location: Michigan Here is some reading for you: http://www.ovationfanclub.com/cgi-bin/ubb/non-cgi/ultimatebb.php?ub... http://www.ovationfanclub.com/cgi-bin/ubb/non-cgi/ultimatebb.php?ub... http://www.ovationfanclub.com/cgi-bin/ubb/non-cgi/ultimatebb.php?ub... http://www.ovationfanclub.com/cgi-bin/ubb/non-cgi/ultimatebb.php?ub...
