You obviously do too much thinking. (smile) Save yourself all the re-engineering and buy an 'aftermarket' dash plate with a DIN hole already cut in it to fit your new radio. If and when you want to convert your car back to original, just change out the DIN bracket for the original two-post OEM bracket. The source for the DIN bracket is Mid-State Delorean's site at http://midstatedmc.com Walt Tampa, FL
