The engine was replaced many times over the years actually! The stock 36hp engine was replaced with a 40hp, then replaced with a 60hp engine, Small but peppy! I have the full car, shell and all. I was wondering if a 1972 super beetle pan can hold and properly fit a 1958 beetle shell. Pics will come soon! I'm in Tennessee, so I'm still awake at like 5:00 in the morning. I will get pics on today!
