Where did you buy the bushings?
There might be a difference between USA Chevrolet (or, GMC) and your Canadian Chevrolet/GMC?
Maybe someone has a Canadian GM truck Master Parts Catalog?
In the USA, the front stabilizer was standard equipment on 1/2 ton panel-body trucks (Panel, Suburban, and Canopy Express).
No stabilizer was standard equipment on 1-ton Panel/Canopy.
A different/heavier ride-stabilizer was standard equipment on USA 1-ton Forward Control Chassis (step van - also called DUBL-DUTI?) trucks.
