Slant six to small block 340-360 engine won't fit.

You won't find a "1970 360 car oil pan" because there were no 360's in '70. Just get a car oil pan AND pick up tube, and you'll be ok.
Jegs, Summit, ebay, they all sell them new or get a used one from here or marketplace or wherever.

Thanks to all - so very much. Those links worked perfectly. already ordered them - and barely over $120 for everything. I can get the gasket from my work, cheap. I appreciate all of you so much. I think I have a new chrome dipstick for it. I went to put it on but it was so much shorter than one that was on it, that I thought it was the wrong. Maybe it's ok. LOL Thanks everyone!
