A 68 power steering setup should work in a 67. The only difference in front end components are the disc brakes; the 67 uses a 65-66 type and the 68 uses a 69 type. Drum brakes are the same for 67 and 68. I would recomend that you get all new hoses. I've rebuilt control valves and it's not difficult. Get a 67 Ford Service manual as it's the best source of information. Most of the rams I've dealt with were bent so I got new ones. If you determine that you need a new pump, get the pulley off. It is special to your engine and car model. You will need special tools to get it off. Also, make sure you get the correct lower pulley.
