TR4 cylinder liners

[Twistblts@aol.com]

Hey listers,
    Anyone have a used set of 86mm TR4 liners they're not planning to use? I 
located a new set of .040 Hepolite pistons and am planning to have liners 
bored to fit them at my local machine shop. Unfortunately, it's a lone way to 
go from the 83mm liners which are stock for my TR3 to the 87mm pistons I have 
located. My engine shop says that it will cost me less to bore 86mm sleeves 
to fit. Any help?

Thanks,
