I am looking at replacing my rear springs in my 67. are the multi leafs really that much better then the mono leaf springs?

 

Multi-springs are "supposed" to be better. However, the perches are different.. At least for the 67. To make it fit I trimmed the side of the top rubber. Car hasn't been driven yet with the 68 multi leafs but the do fit.

 

yes, i know that there are some differences, and that they are supposed to be better, but are they really that much better?
