Can the shocks of a 2003 acura 3.5 rl fit my 1999 acura 3.5 rl

Any time you change the profile or size of the tire you need to consider the problems it throws to the VSS causing the speedometer to be off and the odometer.

The best place to find out if the struts work is to check with a salvage yard. They specialize in cross referencing parts.
