1974 Valiant Rear Leaf Springs (Canada)

Having a ***** of a time finding reasonably priced rear springs in Canada. My local shop wants $245.00 each (includes shipping), and I phone the place that makes them and they want $350 each.

Found some reasonable priced ones on sites like ESPO and others, but once I added shipping we are right back to $600 in no time.

This particular car is my beater daily driver. Is there no off the shelf equivalent for this spring length?

Edit: I have been using peoples advice, and just for future reference did find XHD at dealership and the springs are $194.00CAN each. That is better than I have been quoted elsewhere, and no shipping. I will be looking into what it costs to Re-Arch them.
