I will never forget the first clutch job I did on a Monza with the 262, it sucked so bad that was the last Monza I ever worked on! That had to be around 1979...

They are TIGHT with the factory Y pipe and everything stock in place. They are one of the FEW cars that putting headers on actually HELPS.
