One of the main issues with 68 VB's is that they tend to develop cracks in the areas where the mounting bolts go through and they are not really visible to the naked eye. You can see it on a
vb test machine. If your light on mileage you may be able o use yours again. I usually replace the
VB in high mileage builds. They are a bit pricey but worth it. You do spend quite a bit in parts to build these thing up.
That DNJ piece is nice. Will be on the next one I build.
