Ok here's my promblem and why I ask the question above.. I installed b15 seats in my b14.. what I did for the driver seat is I put the rail from the b14 onto the b15 chusion both parts of the rail bottom and top.. so that way seats fit like stock and I can recline all the way forward for my passengers can get in the back...here's where the promblem comes.. I install the driver seat but it sits real high... I put my passenger seat in the b15 that I didn't touch three of the four bolts line up but it sits a lot lower than the driver so that's why I wanted to kno if I put the nx rails on the b15 cushion will it lower it... if anyone has an idea please post up need help!
