I got mine from
Raw Brokerage - Your #1 source for RB20 / RB25 / RB26 parts!
Its the single best thing I did for my sr's cooling. I used stick on foam (from lowes) to seal the shroud to the radiator. I can literally hold a piece of paper a couple feet in front of the car and it will suck it to the radiator... at idle. lol
Just send them an email and see if they have any.
