Another waterpump conversion thread 'old seal / modern seal'

Not, that I know of any. I manufacture these things myself. BTW. Do you have already purchased a replacement for the destroyed seal? 183759 is much cheaper, than 152051 and fits perfectly as well.
According to FerrariUK (Maranello Concessionaires) it's for later cars, but I think, noone has ever noticed, that it's exactly the same size. Except for a slightly different top configuration, which is less delicate when it comes to installation of the seal.
For this, I could sell you my tool. Where on the globe are you located? If interested, send me a pm (start conversation)d
