Q: The lock I want to replace is 91/2 long by 7/8 wide with a 1 3/4 off set. Will this one work as a replacement?

no, if you purchase the insert lock it comes with lock and key. The unit will fit perfectly into door with no adjustments. the new plates should be also used when installing the assembly. you will be very pleased with the unit.
