What's the combo? You might wanna look into reading the plugs before you romp on it too hard. I love the wheels...my car looked stupid with those on it.
I see i'm not the only one who didn't have the heart to put holes in my dash pad to mount the tach..lol. I got an old column cover and cleaned it up and spray dyed it black and made an aluminum reinforcement for the underside so i could mount the tach directly to the top cover piece instead of using a big hose clamp.
Lol I know just gettn everything cleaned up that pic is really old it minitubbed on 325 drag radials with a nasty SBF with just a hint of spray....
