Upgrading to 11.75ā€ discs on the front?

i will need new calipers too correct? Ive read the 80ā€™s calipers allow the brake hose to be in a more neutral position and the 79 and earlier calipers can put the hose in a bind

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
