New World Datsuns...

Mine flip forward. Just curious, do all 510 seats do that or is that a 2 door only function?

I bought them off CL so I don't know what they came out of.

checked my 72 510 4 dr. They recline backwards only.
think your right about the 2 drs fold forward only.

Thanks for checking yours. These don't seem to go back any further than a normal seating position. When you tip them forward it also releases the slide lock. That's what got me wondering.
