My '67 suffers severe wheel-hop; i've replaced rear springs with BB multi-leafs; still 'hops.
I seem to remember that some company sold akit that welded between rear frame rails on '67/'68 models that re-located upper shock-mounts to 'stagger' them like '69 and later models to helpeliminate wheel-hop.
Anybody heard/seen of this?
thanks

 

try Detriot Speed?
