No, because 1.82:1 was never made. It could be a 1.65, 1.84 or a 1.98, but not a 1.82... If it is one of the others it is a 'simple' job to replace the top gear set with a 1.50:1 set. I say 'simple' because there are a few special tools you need. You'll need a press and a desent torque wrench and a small scale torque indicator. Once you get the drive opened up and start looking at the condition of the gears and bearings you may need new ones of those too, and I would definitely be putting all new seals in. Also a good understanding of what you're doing. What is the year (or serial number) of the drive you want to change and I can point you at the right GENUINE service manual which outlines the procedure...
It may even be cheaper to just buy an SEI top box with the right gears already in. The gear set alone is about $400. Then add the tools and seals... A new top box from SEI is $645....
