either the raising mechanism broke (common on nissans) or the window popped out of place (hope it didn't break). i'm not 100% sure of which setup the 240's have, but if they're like the other 5 nissan windows i've fixed, there's a small plastic tab on a cable that probably broke. it's an easy fix with a little MacGuyver ingenuity though

(i drilled a very small hole and pushed a cotter pin through and bent it around, works like a champ).

SR motor set/clip $2500+, FMIC kit $700+, Downpipe $100+, 3" exhaust $500+, Misc install parts $100+, Shop labor for install $1000+ and you still only make 220rwhp for $5000
so what's so CHEAP about the SR swap again?
