350 GM crate motor oil pan , can't find a replacement

[Junior127]

I have a 1984 gmc 3/4 ton truck with a GM 350 crate motor. The oil pan is leaking but i cant find a replacement at the parts stores and the dealer wasn't any help.

There is a part number on the oil pan, 14101157. I searched on line and it is a valid number but it has been discontinued.

I'm not sure how to determine what motor i have and am having trouble crossing the pan part number. There is a number on the block on the passenger side behind the alternator and in front of the head but i can't find any info pertaining to it. The number is VJ043791.

I'm hoping someone has had to replace a pan like this and can help.

It would be greatly appreciated.

Thanks
