sevill rear disc conversion how to

[dmec]

just finished rear disc conversion and thought i would post how i did it in case anyone is interested. first off the 76/79 seville came in various configurations. ill just cover the basics. it gets too involved. basically small and large frame calipers. im using a combination of small frame backing plates from 76/79 seville and small frame caliper from 82 up seville. they will be on the left side of the picture. the picture shows both small and large frame set ups for comparison.
