count the bolt holes and have a good look at one to see if it will
fit , thats the only way u will find out unless some has replaced one

There are two different sump pans IIRC, the early one which was pressed
steel, and the later one which is cast ally, and was fitted to the engines
with air con.

Yes they are the same as long as they are both steel (no air/con) or
both ally (with air/con)
Peugeot part numbers:

Steel    301F3

Ally   301H1
