273 advise needed

I bought a new oil pan [ chrome] the sides fit fine but, both ends were messed up couldn't use the end gaskets had to silicone them up. I have the original pan had a small crack in it that I brazed up if it helps you out. It's a 273 pan not from a commando if that matters. You're welcome to it just pay the shipping. It's out of a 66 Cuda. Mad Mike
