I live basically on the Quebec side of the Ottawa River. I work in Ottawa, but live in Gatineau...only a 10 minute commute (when there is no traffic)...
As far as the measurements go, I see in the pics that the crossmember is roughly +- 1/2" away from the Coil Spring Saddle. I suppose I could put the rear end in and mount the pivots in place, position the crossmember on the frame and fully compress and extent the axle to make sure it moves freely...the only issue is the "dog-tracking" if I don't line it up properly and equally on both sides. The truck isn't going to see much pavement, but it would be nice if I did decide to put it on the road, it would be going straight!
