hey, i have an ole pulsar vectra year?? in my backyard and i was thinking of pulling the seats out of that to put in my datto as they are a ####load more comfy.... anyway do i just unbolt and bolt in the new rails??

if the dont have the same bolts holes do i just drill new ones???

yeh just drill new ones but be sure to fill the old ones so the Fuzz don't see it, and also put some plate behind it so it doesn't pull the bolt thru the floor if an accident occurs

ah cool thanks alot.... jus measured up the seats and i tell ya what.....

i hope that anyone that sits in the back seats are midgets cause there aint much room there... even with the stock seats

Are you sure the pulsar seats will sit in the 120Y properly? Ive tried 4-5 seats in mine and found that the 120Y has one built-up mounting point on the floor, and a matching indent in the seat so it sits flat. Or do the pulsar ones have the same?

Before drilling your floor pans, try using the stock rails. I always did, no messing with your floor(rust issues and metal colapse).
Keep your rails in place, sit the new seats over the stock rails and measure the discrepancy between the rails and seats. You could drill one side of the rails, and use metal plates to conect the OE holes on the other side (rail) to the seat holes.Or use 4 metal bars, conecting ea/ stock rail hole to ea seat hole. Or you could drill the seats to match the rails. Or you could bolt the seat to a metal bar(one for ea side), and these bars(one for ea side) drilled to match and sit over the rail.Several posibilities, according to what you have available(might be lucky and all holes match, or 2, check it out. Try keeping your OE rails, avoid as much as posible drilling your floor pan.

Yep, I did it the way Jaime recommends.
