I too was looking to replace my oil pan on '73 L-48. I tried a Dorman pan. Unfortunately my oil sump contacted the pan baffle. I have a stock pump and oil sump. If you do replace your pan you may want to make sure the pan clears the sump. Here is a picture of my stock pan with the cutout for the sump. So far I've only found the Corvette original pans for about $250 seem to have the right baffle.
Good luck on your search. Please post or PM me if you find that works assuming you have the same original pan as me.
Jimkari is right about the only "correct"oil pans costing around $250. Zip has an oil pan listed as "absolutely 100% correct" that I'm sure will fit an L48 (not sure it would fit an L82 though). Only problem is it's one of the high priced ones.

I would be very cautious about using a non GM oil pan since even the links above have no pictures of the interior of the pan and the inclusion of the correct oil baffles.
During the rebuild of my 78 L-82 in Spring 2014, I was considering replacing my L-82 oil pan which is different from the base L-48 oil pan with different oil baffles and NO ONE makes a replacement L-82 (Special Performance) oil pan for my year. I opted to straighten my OEM L-82 oil pan and had it painted the correct Chevy blue...all good but that L-82 oil pan is like gold now due to the lack of replacements....
