Zlet oil pump on an early XE crank?

[K24_STE]

Another question for you XE /LET lot, Is it possible to use a Z20LET oil pump if I'm useing a early XE crank? have just noticed that the XE oil pump has a smaller seal on it where it sits over the crank to what the zlet pump has..
Thanks.

The oil seal needs swapping and the mount needs chopping off the top
