what dod you use to plug up the extra port when you removed the recircs? I haven't gotten in there to remove them, yet, but I should be getting the 2nd SSQV any day now, so the install will be soon. I went and picked up 2 1" expander plugs, as I didn't get the 300ZX SQV "kit"... what does the kit come with to close up the extra opening?
