new Hampshire would be the better place to get parts from as there is no sales tax
It is hit or miss whether you get through customs on the way back.
I'm bringing inlet manifold,injectors,engine mounts and a lot of other bits when I go I feb
It is also what allowance you have on the airline
I'm flying with virgin so I've got 1 bag at 23kg and the snowboard bag at 23kg
It is easier to pay the airlines the over weight charge than shipping it back

P.s
If you are anywhere neT the us/Canada border end of Feb look up jay peak in Vermont,thee are 40 of us over there
