TR5/6 Water Pump Seal Sources

[Jeff_Durant@amat.com]

Greetings. 

Does anyone have a source for the water pump seals, large and small, for a 
TR250/6?  The larger is a Pioneer #3315.  The smaller a odd, square 
sectioned with a tapered OD.  Have had zero luck locating either seal. 
I've sent off a quote inquiry to Weston Pioneer in the UK for a modern 
version. 

I'd rather rebuild the original water pumps than deal with aftermarket 
"junk".

Thanks, 
Jeff
