Fair price for front disc brake conversion

I'm in Ottawa and have a good pair of spindles w/caliper brackets for $100. They will need to be cleaned up and painted.

(they are 73+B,R,f,M,J spindles. The calipers brackets are for the 10.89" disks)
all the other associated parts are available at your favorite parts stores.

Probably the easiest way but then you're looking at different front wheels with the later 5x4.5" bolt pattern.
