Hydrovane 504 impeller assembly, same as 502?

[Tiggy_dorset]

I need an impeller for my 504. I have seen listings for 502, but would this fit a 504, or are they different items?

Alternatively there is a Hydrovane specialist in Poole I will be calling tomorrow, but thought I'd ask here first.

Thanks.

Make sure you are sitting down when they tell you the price. I had one years ago & the price of parts was astronomical.
