Alright so after some searching here and dsm tuners I still can not find if anyone has installed 3g seat belts in their 2g before. Reason I am asking is there is a set of black ones in a junk yard near me. And well they are black and look like they will bolt up. I just want to know if anyone has done this before or known of it being done.

The seatbelt "crank" (the mechanism) should be the same. But I dont know about the lenght of it and such, also the brackets that bolt onto the chasis may not be the same.

I dont know if they will fit but If you try to make them work you will need the male and female ends from the 3G. I had 3G seats in my RS and the ends of the 2G seat belts wouldnt plug into the female ends on the 3G seats so I had to swap the female ends from my old 2G seats.
