A former Queens building super faces 75 years in jail after being convicted yesterday of plotting to sell weapons to Hezbollah terrorists.

Patrick Nayyar, 48, showed no emotion as jurors found him guilty on all counts after about two hours of deliberations in Manhattan federal court.

Court-appointed defense lawyer Sam Talkin said he was “disappointed” with the verdict and said Nayyar would appeal.

Nayyar, an illegal alien from India, was busted in 2009 after getting caught in an FBI sting operation.

The feds said Nayyar and an accomplice sold an informant a handgun, a box of hollow-point bullets and a truck they believed would be used to transport missiles.

They also allegedly conspired to sell the informant more guns, ammo and vehicles.

A co-defendant, Conrad Stanisclaus Mulholland, remains at large.
