bianchi strada
 

i got this bianchi with a fluid trainer from cl. looks like 1987 [?] strada, cr-mo lugged frame, sugino vp crank, shimano fd-z202, rd-l532, suzue sealed tech rear hubs and araya 27 1 1/4 rims. the drops were steel and the side pull brakes look like a noname brand. i am swapping the bars for alloy and the front brake for a dia compe side pull. i would like to change the rear to dia compe but it needs the blind side of the brake hole bored out to fit the dia compe nut. maybe i could use a 90 degree chuck on my drill motor or find a longer axle that would use a hex nut?
1. year?
2. mount dia compe rear side pull brake?
