The most trim line
oil pan I have seen was one built by Armando in the Los Angeles area for about $350. You can do a search on this site for his address and telephone number.
How much clearance do you have between the bottom of your
oil pan and the pavement? I think your
oil pan is probably about 6" in overall height (top of gasket lip to the lowest point on your pan base). My pan sets almost 4" off the ground and speed bumps scare the sh_t out of me. You may need to crank up your coil-overs a bit to get the clearance you want. However, there are always compromises with anything you do.
Good luck.
