"don't know where you are
"don't know where you are at but you will have to have it shipped to you if your not in NJ. It's a 79 motor then any oil pan up to 93' will fit. i believe the newer ones would fit also but i don't know for sure.
You also need a 4 piece gasket set. ebasic has it, the gasket set, wholesalemarine, go 2 marine also.
Doesn't matter merc or omc, but the merc one uses one quart more. So be aware cause the dipstick will show different.
When you put the 5 quarts in if it's a merc pan just run it for 5 minutes and pull the stick and mark where the full mark is with a nail or something.
ebay is the best place to find a used one new 350 dollars maybe a little less.
you have a custom auto store near you and they look up a 2.5 chevy II that pan will fit, just paint on the outside whatever you do get 3-4 coats is what i painted mine.
Kodiak custom in Nj got me the timing cover i painted that 4 times before i installed it on my 3.0."
