looks like fun.
Is that a V6 I see?
What size, 351, 401, or?
The shake in the front end was probably worn out king pins, tie rod ends, drag link ends, and possibly the steering gear too.
I have an old Chevy car, 1928, that does that, go over a bump in the road and the whole front end shakes until you get the car stopped and start over.
