I have a '67 coupe 4 lug, 6 cyl. I want to put 5 lug disc on the front. I found a Granada setup complete with proportion valve, master cyl. And Spindles, that is currently on a '66 for $200. My question is... Other than completely replumbing the brake lines. Is there anything else that is gonna give me a hard time ??????

 

Mostly, but you will also want to get the entire steering setup from that '66, as the tie rods will not work with your 6 cyl steering. Drag link, pitman, steering, inner/outer tie rods and sleeves have to be done as a whole. You can keep your steering box and column, just bolt the steering arm to the box.

Other than that, bolt that stuff right up. Pops right in, I think. Ball joints are the same, control arms are the same, for v8 and i6 cars in '67. Connect the brake lines as needed, bleed the system, off ya go.

Plenty of articles about doing this exact swap are found in Google, so there's help out there if ya need it. Good luck!
