Anyone know of a source other than Vortech? They want $400 minimum to change the seals. They won't send them to me, they want me to send the unit to them. They will not warranty my claim as I bought it from a private party, even though the S/C was not used. I assume that a seal is a seal, but I just gotta get the right size. Oh and BTW- Screw Vortech! I wouldn't piss on them if they were on fire!
