Overhaul gasket set for 20 valve silvertop

[Jimmy Hoffa]

I need to rebuild my 20 valve silvertop. I have the toyota part numbers for the valve grind and full overhaul gasket kits. One of my local (Ottawa) toyota dealerships says the numbers are no good, and that they can only get "canada destined parts" I've gotten other 20 valve parts from the same dealer, but cap and rotor are probably common worldwide parts. Does anyone know of any candian dealers can get japanese destined toyota parts? I can provide all the part numbers, I just need someone in canada to buy parts from. I found everything I need from toysport in california, but I'd rather not have to pay shipping and customs charges and worry about exhange rates. Thanks
