[Ray in La Mesa]

I put an "A" pan on a "B" engine, the only difference is the larger rear main cap. I had to enlarge the semicircle to fit the cork gasket on the main cap. It's a little tricky but it came out fine, you have to figure how deep to to make the pan lip press into the cork. Also I used the stock rod nuts which hit the pan sides so just did little metal bumping to the area affected (this was 30 years ago before I knew about smaller rod nuts).
