Early FJ40 seat belt anchors? (4 Viewers)

[VA Mountain FJ40]

On a 1968 FJ40, what do the driver and passenger seatbelt bolts anchor into? Threaded inserts in the tub floor? Big captured nuts?

When I reach under the tub beneath the seatbelt bolts, whatever they are anchored into is inside a tubular cross member. Can’t find a drawing. Only have a bolt head inside the passenger tub.

Worried if I start to remove seatbelt bolts and end up confronted with a spinning bolt with inaccessible bottom fasteners.

Any illuminating thoughts?

Thanks,

I have 68 and I think those are welded and not, simple capture nuts. Spray them down good with penetrating oil and you should be OK.
