if it had a radio in it you can install a cd player easy if not you can cut dash plate by drilling a hole and a saw done it many a times had one in a 52 you can put one in a 67
the wiring and thing's wont be hard but finding the housing for the deck to fit the dash thats not going to be easy , best off getting it installed should cost about 75$ and then it's not really your problem. but more the installers job
Here's a link to a mounting kit I used one just like it in my 1966 ford F100. You can use it under the dash or overhead between the visors witch is whit I did but I have seen people turn it upside down an mount it on the dash over the factory speaker in the center of the dash an run the wires down through that speaker hole then get some speaker box carpet an cover over the dash an kit. Cutting the dash is hard an it never looks that good. It always looks like cr*p an you can't uncut a hole. I hope this will help you or give you some ideas. Good luck.
