TXLNGHRN Jun 24th, 04, 10:47 AM What is the difference, if any between 66 chevelle big block springs and 70 chevelle big block springs????? The a frames are the same so woud the springs be the same too? TimC Jun 24th, 04, 11:34 AM Not sure if 70 springs will work or not in a 66, but I know 66 springs will not seat properly in a 70 as they do not have the flattened coil for the upper pocket. What year is your car? TXLNGHRN Jun 24th, 04, 5:17 PM I have a 70, the A Frames are out from under a 66. I've checked and the A Frames will fit. Wouldn't the springs fit as well? TimC Jun 24th, 04, 5:53 PM 66 springs will not work. The upper pocket is different on your 70. TXLNGHRN Jun 24th, 04, 6:13 PM OK I am putting A Frames from a 66 on to a 70. The springs that are in those 66 A Frames will not work once under my 70. Correct? I hate to sound ignorrant but I need to replace the small block springs that are al ready on it with big block springs, which I got when I bought the 66 A Frames. Thanks for your help TimC Jun 24th, 04, 6:26 PM Originally posted by TXLNGHRN: OK I am putting A Frames from a 66 on to a 70. The springs that are in those 66 A Frames will not work once under my 70. Correct? That's right. 66 Springs will not seat properly in the upper pocket on your 70. A-arm pocket is the same through the years. If you use the earlier springs in your 70 they will rub and squeak. 66 springs = no flattened coil for upper pocket 70 springs = flattened coil for upper pocket At least that's how I understand it. Dale_I Jun 24th, 04, 10:16 PM According to Hollander front springs are interchangable on 64-67 models and 68-72 models. I know the bushing sizes for 64-66 are larger than late 67-72 also. | ||
