Will any IS300 rear suspension fit on 04 gs300

I want to do a full refresh of my rear suspension due to previous owner neglect but trying to get my hands on rear upper control arms for a reasonable price is proving a hard task so just wanted to see if any parts of an is300 will fit.
thanks

Yes, upper arms are the same fitment for 2GS and 1IS.

GS or SC430 OEM arms are more expensive than IS300 or Mark II because they're forged aluminum vs stamped steel.
