The 70 Mustang stuff would be by far the better choice. Make sure you get the outer tie rod ends.I want to change my 68 Mustang from drum to disc breaks and found a front break setup from a 70 Mustang and a set up from a Grenada. Which one would be the better choice?
GOOD JOB BERT!!!!!!!!!!!!!!!Although I'm no expert, and I'm sure someone will correct me, if I'm wrong..... With the '70 mustang set-up, you should be able to fit 14" mustang wheels, whereas the Grenada brakes will not allow this. I believe both sets will require you to change your tie-rod ends. The '70s should mount up the same as the factory '68 disc brake spindals, only having Larger spindals,and bearings..... Hope this helps, in your decision.....and God forgive me, if I've misstated anything...LOL
