Things you Find

Well the Matts agree completely on this one!
A new engine harness would be a good way to approach this.
I got away with using my 67 Barracuda's original /6 harness with the small block v-8 for a number of years.
Then I bought an engine harness from Year One.
Keep your original if you do so.

Is your Barracuda a RHD or LHD model?
