Do you mean to replace with an original style radio? I obtained an original dash cut from a ruined dash but never proceeded with the swap when found the 'fully rebuilt' 1978 radio didn't appear to actually work at all. But I'd imagine the swap would be even easier with an original dash. It's require some grafting and perhaps a border in matching dash vinyl, but that is largely hidden by radio bezel also. I also saw somewhere a while back a moulded plastic or fibreglass perhaps, radio mounting plate for those doing this exact swap, although it may have been a universal size, the idea was still there and possibly of use to mount something to. The original radio used a mounting bracket also, they were super heavy.
