artishard116 Posted February 16, 2019 Share Posted February 16, 2019 (edited) This is kind of a strange one. Test fitting my new frame rails from BD which state they are interchangeable side-to-side, however the stock passenger side rail on my '76 280 is totally different than the driver's side. On the inside edge facing the trans tunnel it is flat along the floor unlike the other the other rails which are contoured. It's also 1.5-2" taller on that side, so if I were to fit the replacement rail over it, it wouldn't reach all the way up to the floor. I've found a couple threads from 2008 referencing the same issue. Can anyone that's installed these on a 280 comment on how they got around this? Measurements in the below pics are taken from both sides of the same rail (passenger).

socorob Posted February 19, 2019 Share Posted February 19, 2019 Just push it as far up as possible and use a block to scribe the shape of the bottom of the car to it. Then get out the grinder. Quote Link to comment Share on other sites More sharing options...
gnosez Posted February 21, 2019 Share Posted February 21, 2019 ....or figure out where the BDP rail stops matching up with the floor contour and take measurements of the width, height and length so a replacement section can be made... Figuring why there are 280Z coupes out there with 2+2 passenger side longer rail would be nice too. Quote Link to comment Share on other sites More sharing options...

It would have to be a piece that spans the whole length of the rail on the trans tunnel side, contours to meet the bad dog rail, extends up an inch and a half or so, and then runs flat along the floor. For the price I was hoping these would at least be the right shape. Quote Link to comment Share on other sites More sharing options...
