Oil Pan and Drag Link Interference 8BA in 36 Cabriolet

[36cabrioletfrank]

This is my first post - 36 Cabriolet with an 8BA engine and 1937 steering box. See attached pictures.

I think my oil pan is from an 8BA truck engine. Can anyone verify this from the pics below?

My drag link has been modified to clear my oil pan. When I hit a bump in the road, it clanks pretty loudly. If it breaks, it's a serious safety issue. I would like to find an oil pan that would allow me to install a straight, unmodified drag link. Is that possible? Will an oil pan from a passenger car 8BA, 59AB, or earlier flathead engine solve my problem?

I think the early flathead engines had a road breather opening in the oil pan. If I found one of those and welded the breather shut would that work?

Will any non-8BA oil pan accommodate my existing oil pump and pickup?

Thanks for your thoughts and advice.
