Upgrading to 11.75ā€ discs on the front?

Iā€™m not aware of the brake hose hole moving from 79 to 80.

call Dr Diff or email him with a picture of your calipers

i just got done talking with cass from dr diff, great guy! He told me the 80 and newer style calipers for rear mounting them for the cleanest and most bind-free hose routing otherwise the 79 volare calipers i have would have to remain upside down.
