Hi Charlie, mostly because it is a M II front end that was added to the chassis before I got involved. The owner did a decent job installing it. I really hate to pull the rack, it would be much simpler to install the flow control. I have read a lot about the T-Bird rack being more compatible with the pressure of the GM Type II with good results. I know this has been hashed out many, many times but there does not seem to be a definitive answer, everyone has an opinion and we all know what one person perceives as fine is not necessarily the best. I have read many threads about the flow control and pressure on the rack when I know that what the person is describing is castor and other alignment issues. I have never heard of installing a GM rack on a Mustang II front end, is there something that works well?
Roger, I am glad you mentioned the flow issue because there is a difference between the flow and pressure. Billet Specialties advertises that their flow control will cut the flow to 2 GPM, which is more desirable for the M II rack. They claim it works well and stops the twitching. I have never seen this rack in operation but I know it is 40 years old and would be a lot easier to replace before the cab is installed. Advance Auto has a Cardone Reman rack # 22-215 for $67. With a 30% coupon it will be hard to pass it up. I just don't know if this is the correct rack to replace the M II rack. I was hoping that someone on the forum would know.
