Fold Down Rear Seat Install
 

Has anyone ever tried installing a 67 fold down seat in a 68 convertible? Other than changing the way it clips in on the top. Would it work?

As long as you don't use the '68 latch, it will be fine. And you would need to use '67 upholstery as the '68's have the 'notch' for the latch. Everything else is pretty much the same.

I don't have the 2 holes drilled from the factory back there for the hinges. I do see 2 pockets in the area for location. Does someone have a picture or a measurement where to drill to mount these hinges?

I did pick up the 67 latches from Ames to hold the seat in place. thanks

Sorry, I don't have any pictures, but there is like a triple bend in the hinges, and they really lay and form against the seat pan quite nicely. When you play with that fit, you will discover there really is only one place they can go.
Check it out. I did one car with original hinges, and two others with repop hinges. The repops fit identically to the originals.

The hinges mount to a pair of weld in brackets that have a slot and a threaded stud.
