krh427 10 Report post Posted July 27, 2010 I purchased a Martz front suspension for my 69. The Martz info has the 67-69 with a 58" front tread width and a 70 with a 60" tread width. I would think that a 69 and 70 should be the same. The 58" width looks too narrow on the 69. Does anyone know the correct tread width? I have seen figures from 58" to 61" on different web sites.
