Welcome to Allpar. 4879188AA is for '01-'02 JR with SDA (base) suspension. Dealer list is $99.
4782998AC supersedes to 4782998AD and is for '01-'06 JR with SDE (sport) suspension. Dealer list is $33.
I would have to run your VIN to see which suspension you have, if it matters.
Physically they should both be similar. The valving is different.
Rockauto or ebay shocks should work OK.
The aluminum upper shock mount on these disintegrated in the salt belt and may need replacement. The new ones are steel.

It is SDA-normal suspension. You may not notice any more 'stiffness' in the ride going with the sport (SDE) shocks as the sport suspension would also have the sport springs.
If you are replacing the shocks for a clunking over bumps, you may want to examine the aluminum upper mounts first. The noise may not be from the shocks.
If you want to PM me with a return e-mail address, I can send you the summary and option list on your car.
