I am looking to replace the seats in my 1970 GT Junior with ones from a unifacto model. The problem is that the captive nut holding the drivers seats front left rail has come adrift. Removing it is no problem but refixing the seat is taxing me somewhat. Has anybody come across this problem and have a solution or a clever idea? So far as I can see the nuts are shielded underneath by the chassis rail so access is not possible.

Thank you.

All I can say is that it was a real ***** to get the sparco seat screwed in place of the original... the front was a breeze compared to the back... hours of wiggling fingers and probing with small objects to get the nut screwed in place... I firmly tightened the front and just left the back screw hanging... sorry...

Gotcha, they are supposed to be floating captive nuts, not true captive.
Sounds like the nut has rounded its corners or the cage has been deformed outwards.
Did you get the bolt cross threaded on reinstallation?
That's the only way I can think the above could happen, in which case you could dremel off just one end of the cage & replace the nut. If concerned about weakness, have the end of the cage welded back on but if it's just one of the mounting points it'd be OK without I reckon
