Jeff it appears that I was wrong on the 1.125 sway bar on mine. I am including picture you requested of it. It just under or over 1 inch in Dia.
Adjustable "E"’s were shocks made by the Gabriel Shock Company in the 60's and 70's that were three way adjustable and 1.625 inches in dia. Since my original shocks were the same color (white) and adjustable, I am assuming that Ford used that shock. There were no markings on my shocks to indicate that was the case. During this time period Gabriel was the only shock company that made a shock that was 1.625 inches in dia. too. Monroe and other private label manufactures only made the traditional 1 inch shocks. It would have been a lot cheaper for Ford to buy them from Gabriel then build shocks to use on 2,000 plus vehicles (Mustangs and Shelby's). Since others are saying CHP vehicles are Ford's version of the Shelby suspension wise. I will assume they had them too.
Production on my vehicle started April 20, 1967, the rolled inter fender lip was noticeable to me back then after seeing others of that time period driving around with their inter lip below the wheel cutout. The result to backing and turning the wheel as the groves on the tire caught the edge of the inner lip. Also having had that same problem on my father's 65 GT, I figured I’s have to bend them up myself. Wider tires helped, but depending on how hard you turned the wheel you could do it with regular tire too.
As for getting Marti to provide an engine break down for CHP vehicle that would be great. Attached is what he provided for me. I am not sure if he’s saying two CHP vehicles were produced with “S” code or two of the “S” code in Acapulco Blue can with CHP. Before anyone asks there were two reasons why I picked the “S” over the “K”, first was warranty “K” code 3,000 miles or 90 days, “S” code 50,000 miles or 3 years. The second my father’s 289 got 10 to 15 MPG. I figured the big block in the lighter body would get better mileage, I was correct 12 to 16. The 16 did not make a difference if I did 65 or 120.
As I stated earlier I did not notice the car sitting lower than other mustangs until a neighbor asked why it was lower than his. This was in 1968 -1969 time span. Long before people started making lowering kits and other ways to make ones vehicle their own. After 46 (unrestored) years it still looks and sits at the same (close to) height and does not show the signs some Mustangs have, of having the front higher than the rear. It seems harder to get in and out of it these days, but I think that is more my problem than its. I’m not in my 20’s any longer. Not quite showroom condition, but close.
