I was at a recent car show and there was a guy there with a white 1953 corvette with a 1960's ChecyV8 installed and the same automatic transmission that is in my 230SL. He bought it from an estate sale where the original builder had passed away. The car originally came with a straight 6 cyl and a 3sp manual. He didn't know what the trans was until I told him. Wish I took a picture. What a Frankenstein !
