WTB 3/5 drop parts. CANADA

[WB72]

I have a couple of months to get the suspension on my converted C-10 lowered. I would like to do this all at once. I have upper and lower control arms, stock spindles with 5 bolt discs on the front. A 3.73 Posi in the rear.

I am looking to buy drop parts Spring and Spindles and possibly Blocks, to be sent to CANADA .

I know you are all thinking that there are no vehicles that can travel in the north during the winter, but there are lots of dogsleds that are employed by the postal service and companies like UPS and FED-EX that come up here every day. (they are real troopers aren't they).

Are there any out there?

New or used will suit me just fine.

Also, are there any springs that interchange from other trucks or cars that will give an altered ride height that I am looking for?
