Hi Dave, not had your email sorry, just to keep you updated i have taken the bits to a local engineering company , they are going to price making a batch of 10+ dependent on interest , phosphor bronze bearings under size to be reamed out when pressed in , stainless steel spindles .
I have also contacted 2 foundries about casting new impellors in either bronze or brass , these will be the webbed type in the pictures above , once cast they will have to be machined by the same engineering company .
My dad had also sourced new packing for the pump seal, I will be looking for this through his garages over the next few weeks so save having to research and find an equivalent.
My father sadly passed away earlier this year and I have inherited his astura , he bought the car as a total wreck in 1979 , photos of it are in the LMC legends section of this forum (Morris Parry), the car has not been used for a few years until recently and I am trying to sort out a few jobs on it including the pump, as soon as i have prices i will post on here or give me your email address and ill email you, j
