hey i got buckets out of a gto (same thing) as the 1970 chevelle ones and i used to ahve a bench in my car and im having the hardest time trying to mount them properly i even got all the seat brackets from npd and they didnt come with any damn instructions so if someone could help that would be nice.

I'm not sure,but someone will correct me if I'm wrong.But I believe the only original bolt holes you use are the rear outside on each seat.And also a guy showed me on his 70 that all the rear holes are in a straight line with the seat belt bolts.Anyone know if this is correct?

Justin, my outer bolt holes lined up with the seat. The conversion kit you bought fits the inner tracks buy the tunnel. You bolt the adapter or weld it to the floor then put your seat on the adapter and bolt it.
