Tonight I just noticed that there are several different sway bars on the 61-63 cars. Till now I thought they were all the same. It also looks like the parts book is wrong. It lists that all 62 f-85 are the same except for police cars. In 63 it shows one for f-85 and another one for f-85 convertible and Jetfire. I got to looking at all my cars and found both of my 62 Jetfire have the same sway bar as the 63 f-85 and is larger than the 62 Cutlass. I then checked my 63 Jetfire and it is the largest of all of them. Funny that the parts book only shows one for 62 other than police. Makes me wonder if I should put the 63 Jetfire bar on my car. I won’t just because i am a purist but I may do it for temporary just to see if I can tell a difference. The back may get looser with the larger front bar
Wonder if the spring rates are diff for the diff bars? As far as being a purist, those were the days when you could order things like sway bars, HD cooling, stiffer springs etc etc on a car that didn’t “come” with them as stock. If it was available, the factory would equip the car as desired in many cases.
OK, I measured some bars. I thought our 62 Jetfire had a different bar but turns out that the thickness is all the same for the 61-62 other than police. The part I find funny is that all three of my 62 Jetfire have an identification nub on one end and the Cutlass version does not have this. Not sure the reason for this. I am going to use the 15/16 bar on our 62 4 speed car and see if i can tell a difference. I am a purist but this is easy to switch back. I did have to get bushings for the 64-72 cars to get a hole large enough.
61-62 bars are 13/16
61-62 Police car bars are 7/8
63 f-85 and Cutlass are 7/8
63 Jetfire and Convertible are 15/16
